(20014)internal Error: Proxy: Error Reading Status Line From Remote Server
Proxy Error 502 “Reason: Error reading from remote server” with Apache 2.2.3 (Debian) mod_proxy and Jetty 6.1.18 up vote 47 down vote favorite 24 Apache is receiving requests at port :80 and proxying them to Jetty at port :8080 The proxy server received an invalid response from an upstream server The proxy server could not handle the request GET /. My dilemma: Everything works fine normally (fast requests, few seconds or
Proxy-initial-not-pooled
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

Perhaps your access pattern raises some kind of flag or you're hitting a bug in the web app such as a missing item in the database that has never been spotted. –Alexandre Jasmin Mar 12 '10 at 5:36 And from what I understand you are doing more than just parsing but something like web crawling. Or are you re-accessing the same URL each time? –Alexandre Jasmin Mar 12 '10 at 5:40 thats all okay how can i parse this page now?? –developer Mar 12 '10 at 6:04 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote Why don't you use CURL to fetch the page contents and then parse them? let me know if this works or you need any help. --Pinaki share|improve this answer answered Mar 12 '10 at 6:39 community wiki pinaki iam doing this using CURL only... –developer Mar 12 '10 at 10:53 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign
