Description Christophe Yayon 2005-12-03 13:40:17 UTC Hi all, I have configured httpd-2.2.0 (release) with mod_proxy and virtual hosting and when i stress it, even low (10 simultaneous users with Mercury Load Runner) i get some errors messages and status code 502 on the client browser. The problem occurs only when i do some load tests, when i request from single client i have no problem...

caching abilities. If you want to set up a caching proxy, you might want to use the additional service ah00898: error reading from remote server of the mod_cache module. Thus, in order to get the ability of handling HTTP proxy requests, mod_proxy and mod_proxy_http have to be present in the server. Warning https://bz.apache.org/bugzilla/show_bug.cgi?id=37770 Do not enable proxying until you have secured your server. Open proxy servers are dangerous both to your network and to the Internet at large. Topics Environment Variables Request notes Directives This module provides no directives. Bugfix checklisthttpd changelogKnown issuesReport a bugSee also mod_proxy mod_proxy_connect Comments Environment Variables In addition to the configuration directives that control the behaviour of https://httpd.apache.org/docs/2.4/mod/mod_proxy_http.html mod_proxy, there are a number of environment variables that control the HTTP protocol provider. Environment variables below that don't specify specific values are enabled when set to any value. proxy-sendextracrlf Causes proxy to send an extra CR-LF newline on the end of a request. This is a workaround for a bug in some browsers. force-proxy-request-1.0 Forces the proxy to send requests to the backend as HTTP/1.0 and disables HTTP/1.1 features. proxy-nokeepalive Forces the proxy to close the backend connection after each request. proxy-chain-auth If the proxy requires authentication, it will read and consume the proxy authentication credentials sent by the client. With proxy-chain-auth it will also forward the credentials to the next proxy in the chain. This may be necessary if you have a chain of proxies that share authentication information. Security Warning: Do not set this unless you know you need it, as it forwards sensitive information! proxy-sendcl HTTP/1.0 required all HTTP requests that include a body (e.g. POST requests) to include a Content-Length header. This environment variable forces the Apache proxy to send this header to the backend ser

There is one public Apache server that proxies requests to these servers. These servers are http://www.gossamer-threads.com/lists/apache/bugs/314332 not directly visible from internet. Some of these servers run IIS and ASP.NET web applications. When accessing these servers through internet then sometimes Apache reports a problem: 502 proxy error. After some digging in error reading internet I found out what’s going on between Apache and IIS. There is very informative bug report in Apache issue tracker - Bug 37770 - proxy: error reading status line from remote server (null). Comment #17 states reason of error as follows: The problem also only occurs for us when we use an IIS backend device, with an apache its ok. From a tcpdump the only diff I can see from remote server between the two sessions is that the IIS closes the connection when the keep-alive time out is reached with a TCP RST packet, while the apache does a Fin/Ack handshake. When IIS sends this RST packet the next request to the mod_proxy device that’s hits the worker with the RST connection returns the 502 error msg. So, there is some misunderstandings between Apache proxy stuff and IIS. Although some guys suggest to use very long timeouts and hacks to Apache source code there is very simple fix that works very well for me. Make sure you have mod_env enabled and add these lines to Apache configuration file. SetEnv force-proxy-request-1.0 1 SetEnv proxy-nokeepalive 1 After restarting Apache server the communication between Apache and IIS should work fine. After these modifications I have seen no error 502 anymore.
