502 Proxy Error Error Reading From Remote Server
(fast requests, few seconds or few tens of seconds long requests are processed ok). Problems occur when request processing takes long (few minutes?). If I issue request instead directly to Jetty at port :8080 the request is processed OK. So problem is likely to sit somewhere between Apache and Jetty where I am using mod_proxy. How to solve this? I have already tried some "tricks" related to KeepAlive settings, without luck. Here is my current configuration, any suggestions? #keepalive Off ## I have tried this, does not help #SetEnv force-proxy-request-1.0 1 ## I have tried this, does not help #SetEnv proxy-nokeepalive 1 ## I have tried this, does not help #SetEnv proxy-initial-not-pooled 1 ## I have tried this, does not help KeepAlive 20 ## I have tried this, does not help KeepAliveTimeout 600 ## I have tried this, does not help ProxyTimeout 600 ## I have tried this, does not help NameVirtualHost *:80

Some reasons why this might happen: Tomcat may have crashed The web application did not respond in time and the request from Apache timed out The Tomcat threads are timing out A network device is blocking the request, perhaps as some sort of connection timeout or DoS attack prevention system If the problem

href="../mod/mod_proxy.html">mod_proxy Status:Extension Module Identifier:proxy_http_module Source File:mod_proxy_http.c Summary This module requires the service of mod_proxy. It provides the features used for proxying HTTP and HTTPS requests. mod_proxy_http supports HTTP/0.9, HTTP/1.0 and HTTP/1.1. It does not provide any caching abilities. If you want to set up a caching proxy, you might want to use the additional service 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 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 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
