I am using Apache 2.2.22 on Windows Server 2003 64 Bit, using PHP 5.2.17. System Specs are 4 x 2.0 Ghz processor, 4 GB of Ram.
I'm noticing when I load my website [URL] .... there is about a 2000ms delay before the page starts to load.
How can I make Apache load faster?
I'm running Apache 2.4.4 Win32 on a Windows 2008 server. When trying to optimize a website I noticed a random reoccurring 2550ms delay in Time To First Byte. A file could have a TTFB of 200ms several times but suddenly it would get 2750ms. This could be a static file (image, html, js) or php. I've measured using ApacheBench (locally and remotely), webpagetest.org and bytecheck.com. After much trial and error I found the problem was with mod_rewrite. Disabling this and everything is fine.
I have setup a blank/new install with only basic config change (Listen, ServerRoot etc) to replicate result without anything else interfering. Following is the rewrite section I add to config.
Code:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule (^/Pictures.*) /$1 [L]
</IfModule>
After Apache has started I execute "ab http://my.example.com/Pictures/Thumbnails/tmb_400X400_FFFFFF_660.jpg" and always get the delay. If I execute again it's normal. If I wait at least 30 seconds I get the delay. Following is a section from error.log with trace8 logging.
Code:
[Tue Mar 12 23:28:56.123519 2013] [rewrite:trace3] [pid 7624:tid 888] mod_rewrite.c(468): [client 69.x.y.90:36279] 69.x.y.90 - - [my.example.com/sid#42c748][rid#26df0d0/initial] applying pattern '(^/Pictures.*)' to uri '/Pictures/Thumbnails/tmb_400X400_FFFFFF_660.jpg'
[Code] ....
As you see from line 3 to line 4 the time skips 2550ms. When the TTFB is normal then the log is identical except time doesn't change from line 3 to line 4. If I delete the rewrite section in config then TTFB is always normal, no matter what.
When I testet on the live server the time for fully loaded increase from 3800-4000ms to 8500-10500ms when mod_rewrite is enabled. And that is about 30 requests (php+css+js+images). So the impact is significant.
What can this be? I'm having a hard time believing it's a bug. Isn't mod_rewrite used a lot? I'm running Ubuntu (linux) at home, I'm going to install Apache there and see if I get the same result.
I am using apache proxypass to proxy to 4 different ports (java/jsp applications) with the following configurations (for each):
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName *****.org
ProxyPass / http://*****.org:8080/ retry=0
ProxyPassReverse / http://*****.org:8080/
</VirtualHost>
Everything seems work fine until an awkward delay / connection timeout occurs. The web application hangs for about 5 to 15 seconds and starts working normally after that period. It's certainly not the application's issue because everything is fine when using IP address to access it.
When I enabled the debug log in apache, I found out that every time the server seems to hang, the following error appears in the apache error log and the number of apache child processes keep on increasing (ps aux | grep apache).
[Thu Apr 11 10:20:41 2013] [debug] proxy_util.c(1818): proxy: grabbed scoreboard slot 4 in child 13208 for worker proxy:reverse
[Thu Apr 11 10:20:41 2013] [debug] proxy_util.c(1837): proxy: worker proxy:reverse already initialized

[Thu Apr 11 10:20:41 2013] [debug] proxy_util.c(1818): proxy: grabbed scoreboard slot 3 in child 13208 for worker http://*****.org:8080/
.....
Also, the access log (access.log) completely stops during that hang period.
This debug message keeps on repeating as long as Apache/web-application is not responding. The application starts to work normally after that duration and the number of apache child process decrease to the normal number.

View 1 Replies View Relatedusing somewhat clever techniques, I've managed to put together a script that will check various rbls, honeypots, and the like, ie: to keep the bad guys out, and the good guys in.
I've managed to put this into play on a per site basis, using simple
PHP Code:
<? require_once("/home/user/httpbl/script.php");?>
so that I don't have to change 500 scripts every time I want to modify it, I just change it once per server. Pretty simple there.
The problem is that I'd like to use this on a more global basis, as in putting it in apache configurations, so I don't have to load it on a per-site basis, and can catch more of what needs to be caught.

We're using cpanel. I'm unsure why it's loading the first domain when you load the IP.
It used to load properly but for some odd reason stopped working. I suspect a cpanel update was the culprit.
Sometime Apache Test Page opened insted to Home page of website, also sometime Network TCP/IP error occured to same site.
I didn't change any setting of httpd.conf last period. also because this problems manily happened in countries which access internet via proxy I check site via [url] and it's working fine

There is a page on a separate SharePoint environment, under http://domain.edu/yyy/yyy/yyy/yyy. We have a subdomain called http://123.domain. edu . We need the home page of http://123.domain,edu to point to the SharePoint site, so when users type http://123.domain.edu , they are redirected to http://domain.edu/yyy/yyy/yyy/yyy.
The trick is this - we need all sub-directories NOT to redirect. So, whatever is under http://123.domain.edu/subdirectory should not redirect at all. Is this doable? Also, if it is, I have no clue where to go to make any changes, so any instructions would be great. So far, I have found the text file httpd.conf that I can edit, but I have no clue about the rest.
I want to add an advertising banner to every web page served.
The problem is I cannot seem to make the OutputSed command recognise absolute paths. I can make it work with a relative path for both the image and the <a> href, but not absolute, which is awkward as the webite wiill have different directories for content created by FTP for hosting results of different tournaments.
This is what I have in my vhost.conf file for the banner image:
Code:
<Directory "/var/www/fencing-results.co.uk">
Options Indexes FollowSymLinks
AllowOverride all
Order allow,deny
Allow from all
AddOutputFilter Sed htm
OutputSed "s/<body>/<body><img src="/var/www/fencing-results.co.uk/banner.jpg">/g"
</Directory>
When running OWASP ZAP web security tool, I get the following flag: Secure page can be cached in browser. Cache control is not set in HTTP header nor HTML header. Sensitive content can be recovered from browser storage.
I was surprised since i had the no cache header in both html code and httpd header.
After investigating the flag, i noticed that the response was a generic 302 found error response from Apach (located in apache/src/modules/http/http_protocol.c).
I have added a patch to code when adding the cache-control & pragma html headers with no-cache - and that had solved the security flag (patch attached).
full response given:
header:

In conclusion:
Issue is "Secure page can be cached in browser." (found by owasp zap) for https page response "302 Found" from Apache.
I'm hoping to redirect visits to any page in an old directory to the index page of a new directory.
In other words, redirect:
[URL] ....

Is this possible? If so, how could I do it?
In my .htaccess I currently have:
Code :
RedirectPermanent /facts/ http://www.domain.com/newfacts/
but this only redirects the index page.
I can't access to some alias page by URL....

Wordpress installation (WPML with 3rd level domain es. site. com, fr. site. com).I need to redirect page from old subdomain to a new subdomain
Example:
esp.site.com/oldpage -> es.site.com/newpage (different subdomain)
esp.site.com/oldpage1 -> es.site.com/newpage
esp.site.com/oldpage2 -> es.site.com/newpage
Source site is very chaotic (static pages + wp pages) and there are no clear rule for redirection (no regex ).So I need to redirect every single page but syntax:
Redirect 301 esp.site.com/oldpage http:// es.site.com/newpage doesn't work!I think "esp.site.com" in source page is not acceptable syntax..which is the correct syntax ? Can I manage all from one .htaccess file in main root (www) or should I create "esp" directory (and point old subdomain to it - one for every language) and put .htaccess in every directory with redirection ?

a question on mod_proxy. We're using mod_proxy as a simple reverse proxy (ProxyPass & ProxyPassReverse) to reverse-proxy various back-end PHP and Mono/.NET apps.
One problem we see is that when the back-end PHP app suffers an error (e.g. a 404 or 500) , then mod_proxy ignores the nicely-formatted custom error page served up by our PHP app, and instead serves a very plain generic mod_proxy 404 or 500 error page back to the client. Is there a way to configure mod_proxy to serve up the 500/404 error page content which is created by the back-end app ?
(We thought ProxyErrorOverride might work, but it seems to be intended for the opposite scenario, where I want to *ignore* the 404 page content from the back-end and show a mod_proxy-defined error page instead.We're using apache 2.2 on 64-bit CentOS 6.5 ( httpd-2.2.15-31.el6.centos.x86_64 )
Config like:
...
ProxyPass /abc/ http://server4/abc/
ProxyPassReverse /abc/ http://server4/abc/
I need to create a redirect to a non existing page.
Here is my code and the site is on shared hosting
<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteRule ^index2.php#!(.*)$ /index2.php/$1 [R=301,L]
</IfModule>
This would be [URL] ....
I would like to redirect Every request with "#!string" to new url (same page) - [URL] ....
I know that the code above needs
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
to be added but it doesnt even makes the redirect to 404. The url doesn't change.
I have the following code in my .htaccess file to block an IP from accessing a file on my site and it works fine.

I'm looking for a way to add a script in the header tag of a web page without using a CMS or anything like that.it should be the first script that is running when the page is rendered.I'm running Apache 2.2.25 and Tomcat 7.0.50 - both Win32 versions.
There are two reasons for an approach like that.
(1) - I expect it to work regardless the CMS I'm working with; the same expectation is for Tomcat and Java applications.
(2) - I'm able to start this as early as possible => includes monitoring the performance of the CMS itself.
I recently configured a Centos 6.5 server with Java JDK1.8 and the bundled Tomcat server X64 application. I confirmed the web server port is not already in use and also installed the Tomcat APR libraires. The application starts fine and all the logs show no severe errors however when I navigate to te URL I see a blank page. All the configuration files are in tthe correct place and whether I use just :8080 or /licenseserver the page is still blank. If I run the element inspector in the browser it shows 404 file not found.
