HTTP 502 Proxy Error
May 7, 2008
Someone tried to access their webmail from a remote location and got a page not found error. It did have the following error like this at the bottom though:
"HTTP 502 Proxy Error - The specified Secure Sockets Layer (SSL) port is not allowed. ISA Server is not configured to allow SSL requests from this port. Most Web browsers use port 443 for SSL requests. (12204)
Internet Security and Acceleration Server"
This is a cpanel server with Centos. I did not find any info via cpanel's forums about the 502 error.

Anyone can inform how to fix "http-put proxy" or "http-connect proxy" ?
My hosting provider said that my dedicated server is not secure because of that.
I use CentOS 4.x and only Apache 2.0.52
# rpm -qa | grep htt
httpd-2.0.52-28.ent.centos4
httpd-suexec-2.0.52-28.ent.centos4
I searched about the topic but got not much information.

I am trying to figure out how to do a setup to convert socks to http.
I have an application which only supports http proxy. I am using putty to perform ssh tunneling but I guess I can only use that as a socks connection.

I have been searching for a non web UK proxy. I need to view UK search results and ads
Should I just use ssh tunneling? If so any suggestions on a cheap UK shell account?

I am using an apache reverse proxy :
httpd -version
Server version: Apache/2.2.15 (Unix)
Server built: Oct 16 2014 14:48:21
In front of an internet liferay server, I m forcing https connexion and my reverse proxy is the SSL endpoint, and it is working fine.
But inside the liferay page there are "http" link to other webserver, and browser are refusing to load them because they are http and not https.
Is there a way in the reverse proxy to rewrite "on the fly" "http" link to "https" so that everything would be load on the browser ?
I was thinking mod_proxy_html but it doesn't seams to do what I want.

I'm running Apache 2.4.7 on a RHEL 6.4 server. I'm using the Oracle WebLogic Proxy Plugin ver 12.c to connect to a back end server.What's happening is that Apache answers URL.. and proxies the request via the WebLogic Proxy Plugin to internal.blah.com. Unfortunately, the downstream system encounters a problem and issues an http 302 redirect to internal.blah.com/whathappened. I would like to have Apache intercept this http 302 and redirect the client to URL...

I recently transferred my domain names from MyDomain.com to GoDaddy.com and now whenever you click on a link to my site from the search results it produces an HTTP 500 Error. I am using HostGator and they said that it is "not what they assist with". I know it could be a number of things but they told me to check with my redirects and there is nothing in the .htaccess file.

I just moved my server from one colo center to another.
The server is running debian and Layered Panel.
The only thing that changed was my two IP's.
Once I got the server up I ran a Layered Panel script
designed for changing IP's ./reconfigure domain IP1 IP2 .
After that all seemed well until I found a problem.
All the free hosted sites on my system work fine unless one
uses www . For example site.myhost.com works but www.site.myhost.com causes a 502 Proxy error.
The same happens for top level domains, freehosted.com works but
www.freehostedsite.com causes 502 error.
A couple lines from my error log:
[Thu Mar 27 20:26:45 2008] [error] [client 86.156.43.42] proxy: DNS
lookup failure for: freehostedsite.com returned by /brit.htm
[Thu Mar 27 20:31:44 2008] [error] [client 69.137.107.47] proxy: DNS
lookup failure for: amour.myfreehost.com returned by

my "Google Webmaster Tools" the other day and came across this in web crawl errors:
URL: [url]
Detail: General HTTP error
Problem Detected On: Sep 13, 2008
"Last updated Sep 16"
Does this mean it detected the problem on sep 13 and it has tried to access the page since then and has been unable to? I've been able to access the page fine between the 13th and 16th?
Anything i should be worried about? "Google last accessed my homepage on the 5th"...

I'm using IIS v5.1 on WinXP SP1 and I encountered this error (Page cannot be displayed.....HTTP 500 - internal server error) all of a sudden. now, i've been using my Web server with no hitches, but now I can't open any pages on the server that run server side scripts so i reinstalled it and still get the same "Page cannot be displayed" or I get part of the source code for the server side script. Pinging the server shows that its ok, it replies. and regular pages with no scripts still run with the http protocol in the address. Any ideas on how to get past this problem?

I have a custom software that runs it's own webserver. I then found instructions on how to use apache2 as a proxy that will enable ssl for that site. (long story short, my custom software doesn't support ssl and it's not an option)

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/

Being relatively new to the Linux world, I don't exactly know why my reverse proxy settings are not working. Nothing i have tried has worked.
The code below is from my old windows server what does not seem to be working in my new 1&1 vps server. I have the below code at the moment at the bottom of my httpd_ip_defult.conf file under /var/www/vhosts/system/mydomain.com/conf/
Code:
ProxyPass /cam http://xxx.xxx.xxx.xxx:8008/cam_1.png
ProxyPassReverse /cam http://xxx.xxx.xxx.xxx:8008/cam_1.png
The following errors also show up in my vhosts error log:
Code:
[Sun Oct 12 23:30:56 2014] [error] (70007)The timeout specified has expired: proxy: HTTP: attempt to connect to xxx.xxx.xxx.xxx:8008 (xxx.xxx.xxx.xxx) failed
[Sun Oct 12 23:30:56 2014] [error] ap_proxy_connect_backend disabling worker for (xxx.xxx.xxx.xxx)
I also have mod_proxy.so , mod_proxy_http.so and mod_proxy_html.so all enabled in my main httpd.conf file at /etc/httpd/conf/
Basically, I need to fix this urgently as a core feature of my site relies on this setup.

My Linux Server's Http Daemon (Apache) would stop serving websites ever so often, as soon as apache is restarted the error fixes iteself only to resurface within few hours.
The apache process would still be running i.e. apache does not die but no websites hosted on my server would be accessible from browser. And when this happens the apache logs do not log any http requests.
Instead when this happens all http requests to my server would be redirected to some weird Trojan website and my Norton Antivirus would show an Alert/Warning, for example;
"Browser exploit at www.xxx.xxx was blocked"
Risk Name: MSIE WebViewFolderIcon ActiveX Control BO
or another error like;
"Auto-Protect has detected Trojan.Fakeavalert".
At first i thought the problem could be with my Laptop/ISP so i logged on to the server via SSH and opened try to open a website using command line "lynx mywebsite.com" and it shows following error;
"Alert!: HTTP/1.0 503 Service Unavailable".
Now if i assume my laptop were to be infected, then as soon as i restart my apache and visit mywebsite.com eveything returns to normal with no such warnings. Why do i see those norton error messages only when apache is down with 503, and when apache is down with 503 how come the http requests always get redirected to some suspicious websites and nothing gets logged in apache error log?
I think my server is being attacked causing http to get unresponsive and thereafter http requests to my server are redirected to some malicious website, is this correct?
Also, i suspect this is a php script exploit as some customers have reported that google have blocked their website due to security reasons, i found <iframe> tage inserted in some php pages which i fixed.
Also, another thinh i noticed;
when apache responds with the 503 it is referencing PHP 5.1.4 in the header response:
[root@]# curl -I xxx.xxx.xxx.xxx (my server ip)
HTTP/1.0 503 Service Unavailable
Server: Apache
X-Powered-By: PHP/5.1.4
Retry-After: 20
I am running PHP 4.3.9m why does apache responds with PHP 5.1.4 when this 503 error surfaces?
Also, since my apache was dowan with 503 error a customer mailed in today saying;
"It seems that my site www.xxxx.com is regularly down, and the winlogon virus is involved."
I suspect this is again due to the fact that http requests start getting redirected?

When accessing a backup in backup-manager in a user subscription via a reverse proxy (eg. plesk panel is called as localhost:8443) I get following error:
Internal error: Failed to exec pmm-ras: (array ( 'code' => 127, 'stdout' => 'Transport error: File 'clients' not found ', 'stderr' => '', )).
Message Failed to exec pmm-ras: (array ( 'code' => 127, 'stdout' => 'Transport error: File 'clients' not found ', 'stderr' => '', )).
File Connector.php
Line 227
Type PleskPMMResponseException
This happens when I try to download the backup and also when clicking on the backup name. These are the apache settings for the reverseproxy domain:
SSLProxyEngine On
AllowEncodedSlashes On
<Location />
ProxyPass https://localhost:8443/
ProxyPassReverse https://localhost:8443/

I'm not sure if this is the right forum, or if anyone can suggest a message board where I might get support on this.
This is what I have. I have Apache and IIS both running on Windows 2k3.
Apache is running in reverse Proxy mode sending multiple domains/virtual hosts to IIS.
Code:
ProxyRequests Off
<VirtualHost *:80>
ProxyPreserveHost On
ProxyPass / http://localhost:8080
ProxyPassReverse / [url]
ServerName mydomain.com
</VirtualHost>
Now, if I type in [url]everything works great and IIS (listening on 127.0.0.1:8080) serves the page. However, I am doing custom error trapping, so when I type in [url](and /mydirectory doesn't exist on IIS) I need to fire ASP code (via custom error messages/handling) on the IIS server and then present a data driven page.
However, Apache is returning A 502 error:
Code:
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /mydirectory.
Reason: DNS lookup failure for: localhost:8080mydirectory
Is there a way for me to setup Apache to pass all error checking to IIS while using it as a reverse proxy?

We have been using Apache 2.2.x with reverse proxy modules for our clients to access their OWA servers for over a year. I want to get us to Apache 2.4.x so I setup a test box with latest 2.4 on it. I fixed the config file issues since 2.4 has changes in it. OWA proxy is working on my test server with Apache 2.4. But with 2.4 I do have an issue I cannot figure out. Note that this does NOT occur with Apache 2.2. I get the following errors when using ActiveSync through reverse proxy:
[Thu Oct 17 12:19:11.670665 2013] [proxy_http:error] [pid 748:tid 8440] (OS 10060)A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. : [client x.x.x.x:20311] AH01102: error reading status line from remote server mail.nameredacted.net:443
[Thu Oct 17 12:19:11.670665 2013] [proxy:error] [pid 748:tid 8440] [client x.x.x.x:20311] AH00898: Error reading from remote server returned by /Microsoft-Server-ActiveSync
So somehow with Apache 2.4 there is some sort of timeout that was not there with 2.2.
