Apache Handles Every Request 3 Times
Oct 21, 2007
New VPS, CentOS 4.5, Apache 2.0.52, Plesk 8.2.
Every request is getting processed 3 times. In other words, if I point my browser to the URL of an image hosted on this server, it generates 3 lines in the access log each time I refresh the page.
If I point it to a script which logs something to a file, it logs it 3 times, showing it's run all 3 times.
I haven't touched the httpd.conf or any other configuration. Any idea what could cause this?

Apache keeps stopping. MULTIPLE times per day! There is no logic to when it dies. But about every 2 hours.
Load stays below .30 and there is free memory available.
This is on a VPS machine. None of the other VPS's are having an issue. Just this one.
Centos release 5.3 (Final)
Apache/2.2.3
Here is what is in the httpd.conf file. I realize the numbers are way too high, but just trying to get this issue to go away.
Code:
<IfModule prefork.c>
StartServers 100
MinSpareServers 100
MaxSpareServers 100
ServerLimit 512
MaxClients 512
MaxRequestsPerChild 4000
</IfModule>
<IfModule worker.c>
StartServers 100
MaxClients 500
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 100
</IfModule>
Here is what is in the /var/log/httpd/error_log file before it dies:
Code:
[Wed Jul 01 18:06:32 2009] [info] server seems busy, (you may need to increase StartServers, or Min/MaxSpareServers), spawning 8 children, there are 98 idle, and 108 total children
[Wed Jul 01 18:08:17 2009] [info] server seems busy, (you may need to increase StartServers, or Min/MaxSpareServers), spawning 8 children, there are 74 idle, and 76 total children
[Wed Jul 01 18:08:18 2009] [info] server seems busy, (you may need to increase StartServers, or Min/MaxSpareServers), spawning 16 children, there are 63 idle, and 63 total children
[Wed Jul 01 18:08:19 2009] [info] server seems busy, (you may need to increase StartServers, or Min/MaxSpareServers), spawning 32 children, there are 79 idle, and 79 total children

when I had multiple (at least 5) vhosts set to Apache when it just hanged, this was fixed adding:
Code:
Acceptfilter http none
Acceptfilter https none
To my httpd.conf, but now it's not hanging, it just times out, I get no error, nothing in the error.log file, it just times out.
After doing a refresh, it comes back like nothing happened.

I am working with XAMPP 5.6.8 (Apache 2.4.4, MySQL 5.5.32 and PHP 5.6.8 ) on a 64 bits Windows 7 Ultimate (Service Pack 1) Operating System.
I am working with an Arduino UNO and a WIFI Shield connected to the Apache server.
I am sure Arduino is connected to the WiFi network and to the server, and it also sends the GET request to the server.
Apparently, everything is OK because I can see the 200 OK message from the server in the Arduino serial monitor, but I find no trace of that request in the server log although all the requests made from the browser (by typewriting the server address in the browser address bar and pressing enter) appear in the server log.

In my web site I have several index pages in different languages in the following format
[URL] ....
Two days ago I noticed increased, many times. Google bot activity on my site and when I checked my log file I found that all pages crawled were wrong web addresses: to the above index were added existing files from my site like
/folder1/folder2/file.html
So, the strings looked like
[URL] ....
And surprisingly all they returned code "200".
My question is: is there any way to rewrite such requests to the first ".html" found in the string.

I have following components configured.
LoadBalancer, Apache and SSL enabled JBoss.
Lodbalancer URL ....
Apache URL ...
Jboss URL (SSL) ...
When the request comes to Loadbalancer, it is forwarding the request fine to apache.
But from apache I am not able to forward the request to Jboss(SSL)
I am using below settings on httpd.conf file of apache but url is getting changed to [URL] .... from [URL] ...
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://servername:8443/EPC [R,L]
I still want the generic name (emsprod.com) to be displayed on url instead of server name.
How I can successfully forward the request to Jboss when I access LB url.

I would like to rewrite mysite.com to www.mysite.com.
However, if the request is a subdomain (i.e. blabla.mysite.com), then it should not rewrite.
I believe this gets me close, but it will not differentiate the subdomains (i.e., blabla.mysite.com).

As we are planning to implement Mobile for our platform, we want to distinguish between request coming from Mobile and Web in Apache. We will be using Apache for Reverse Proxy and we want it to differentiate the request source and forward it to required destination.Is this possible ?

I've decided to move from my current provider (which I have praised many times on this forum before) because I'm just not getting the service I expect.
I'm specifically interested in a provider who is able to upgrade a VPS quickly, efficiently and on time, with no excuses and without "forgetting" things.
If you have experienced more than one upgrade with a provider which has been handled exceptionally well, please point me in the right direction.

I am seeking a solution such that the apache vs 2 denies php or allowing requests out of the server to say domain abc.com and its entire IP block.
I have done so far is used apf -d abc.com to deny outgoing and incoming requests and the php pages (proxies) cannot access the site anymore).
But what i want it something hardcoded into apache itself so it blocks all php based request going off the server to that domain.
How can i go about it?
using centos5 apache 2 and cpanel!

I've been having trouble the past few days with someone who's been "attacking" my site so to speak by continuously downloading very large files with as many connections as (he) can open. I operate a large downloads site for computer games, this person has selected the largest files (like 400-500MB). Not sure of the real intent other than to clog up my bandwidth capacity. Also he appears to be using proxies since as soon as I ban one, another shows up seeminly from China.
Anyway, I have mod_bw and I've limited the number of connections in the downloads area to 2. While that works ok, his tool uses threads like a download manager would and he's using up 30-40 child threads for his 2 file downloads.
So 2 questions,
Is there anyway to not only limit file downloads to 2, but limit the number of connections per request? Many of my visitors do use download managers and I'd like for them to continue using them but use a reasonable number of threads like 6 or 8, but not 30.
Also, is there a way to restrict access to someone using a proxy?

I have an Xitami server and am migrating to apache httpd. I have the regular server working fine. I tried configuring ssl, but no requests are coming through. I know 443 is open on the router because it works fine under Xitami. I checked the logs and it si starting fine. I am attaching my httpd.conf and the startup log. If I try to access the website using https, it just times out and nothing goes in the log file. I replaced my domain with domain.com. I have tried many different examples, but cannot get it to work and am not sure what to do.

So I've set everything up manually a few times before now, but I got so bored of configuring everything for a manual install I just said screw it and used XAMPP this time - so my circumstances are not completely ideal.
Basically what I am looking to find out is how to improve loading speeds for Apache, PHP and MySQL on my dedi server?
The server I have is of the following spec:
Intel Xeon CPU E5-1650 V2 (3.50Ghz with 12 cores total)
64 GB DDR3 ECC
2 x 2TB SATA3 (RAID 0/1)
use Windows Web 2008 R2 so only 32GB of the RAM is usable.
With all the abive aside, here is the important part: Whilst people are browsing the websites I have configured they are random hit with a blank white page saying "Your request has timed out. Please retry the request." - I have about 100 unique hits daily and a lot of people report the same problem, and I have even had it myself.
It feels as if the server has much more power than Apache and co. is trying to utilize - what can I do?

I have hundreds of sites on a server running Plesk. When I try to add more, Apache refuses to start, because it is out of file handles.
It is out of file handles because Plesk includes a custom ErrorLog and CustomLog in every vhost config file it makes. I tried overriding them with a vhost.conf file, but am not sure how to unset set options. I also tried pointing all the same ErrorLogs to the same file, but that didn't seem to do anything.
Does anyone know how I can either log everything to a single file, or just shut off logging? I really never use logging, and it seems like it would save me progressing power and storage (not to mention file handles!) if I could just disable it.

I have a client who's Apache on a CPanel based VPS keep's restarting.
In the error log we recieve two of these lines
"client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFin "
Then the Apache will restart.
I have looked around and found some threads about this problem, but none explaining how to fix this.

I am using the latest version of Apache on an Windows XP machine
When my web service is down for maintenance, since Apache is will still be up and running, I would like for Apache to serve an xml file as a response for the appropriate request. I have three operations available, makePayment, calculateFee, and voidPayment.
Is it possible to have Apache determine what type of request is made for example if I have an xml error page for each operation; how will Apache know which xml file to serve based on the operation request from the client
To make it more clear: What is the best practice for modifying apache to know what request is being made in order to serve the appropriate xml file?

One of the sites I run is a forum with a political component, and 4-5 times over the last week we've been seeing DoS attacks. They're not terribly sophisticated -- generally 1-3 compromised servers throwing packets my way -- but they're enough to clog my pipes and take my sites down.
What I'd like to do is put a new server up at a data center that's D(D)oS aware that can hopefully respond to these attacks automatically. My current provider has been giving solid support, but the best they can do is null route the affected IP, rather than filtering the incoming attack.
Can y'all name a few providers I should look into? Right now I'm just looking to move 1 box (or maybe a box and a firewall depending on the setup).

So I've got a problem where a small percentage of incoming requests are resulting in "400 bad request" errors and I could really use some input. At first I thought they were just caused by malicious spiders, scrapers, etc. but they seem to be legitimate requests.
I'm running Apache 2.2.15 and mod_perl2.
The first thing I did was turn on mod_logio and interestingly enough, for every request where this happens the request headers are between 8000-9000 bytes, whereas with most requests it's under 1000. Hmm.
There are a lot of cookies being set, and it's happening across all browsers and operating systems, so I assumed it had to be related to bad or "corrupted" cookies somehow - but it's not.
I added "%{Cookie}i" to my LogFormat directive hoping that would provide some clues, but as it turns out half the time the 400 error is returned the client doesn't even have a cookie. Darn.
Next I fired up mod_log_forensic hoping to be able to see ALL the request headers, but as luck would have it nothing is logged when it happens. I guess Apache is returning the 400 error before the forensic module gets to do its logging?
By the way, when this happens I see this in the error log:
request failed: error reading the headers
To me this says Apache doesn't like something about the raw incoming request, rather than a problem with our rewriting, etc. Or am I misunderstanding the error?
I'm at a loss where to go from here. Is there some other way that I can easily see all the request headers? I feel like that's the only thing that will possibly provide a clue as to what's going on.

My customer has an external facing Apache server that is acting as a reverse proxy to two internal applications. They have:
- external addresses for each app which resolve to different ip addresses, so app1.their_domain.com and app2.their_domain.com resolve to 77.3.170.10 and 77.3.170.11 respectively.
- the Apache server has two network interfaces with ip addresses 192.168.10.10 and 192.168.10.11
- the external ip addresses resolve to the above internal addresses
- the firewall between the Apache server and the internal app servers is configured to allow traffic from 192.168.10.10 to reach app_server1, and traffic from 192.168.10.11 to reach app_server2, both using port 7777.
I have configured a virtual host in httpd.conf for each ip, i.e.
Code:
<VirtualHost 192.168.10.10:80>
...
ProxyPass /app http://app_server1:7777/app
ProxyPassReverse /app http://app_server1:7777/app
RewriteRule ^/$ /app/app1 [R,L]
...
<VirtualHost>
and
Code:
<VirtualHost 192.168.10.11:80>
...
ProxyPass /app http://app_server2:7777/app
ProxyPassReverse /app http://app_server2:7777/app
RewriteRule ^/$ /app/app2 [R,L]
...
<VirtualHost>
This works fine in that the external address are being routed to the correct application, however the firewall is blocking requests to the second app as it appears the requests are coming from the Apache servers 'primary' ip address 192.168.10.10 instead of 192.168.10.11.
Is it possible to send requests using the ip address from the relevant VirtualHost?
