There's probably 3 or 4 requests going per seconds so we're talking around 1 or 2 out of every thousand that have this error. [Tue Nov 23 11:44:14 2010] [error] [client 172.16.1.31] (20014)Internal error: proxy: error reading status line from remote server soap1.server:8888 [Tue Nov no protocol handler 23 11:44:14 2010] [error] [client 172.16.1.31] proxy: Error reading from remote server returned by /someapp/path/to/web/service This causes the request to fail. If I have the client connect directly to the soap server without using the proxy, success is 100% so the problem appears to be in the proxy The configuration looks like this. The purpose is to switch to a backup server if the primary one is unavailable: BalancerMember http://soap1.server:8888 lbset=0 BalancerMember http://soap2.server:8888 lbset=1 ProxyPass /someapp balancer://apicluster/someapp ProxyPassReverse / balancer://apicluster/someapp Has anyone run into this and found a fix? There's some mentions in bug reports but no solutions. The only thing that may be unusual is the client request could be 100MB or larger, so the request could take a little longer than you'd expect for a SOAP call. apache-2.2 mod-proxy share|improve this question asked Nov 28 '10 at 16:21 JOTN 1,4271612 The answer by David Purdue (SetEnv proxy-initial-not-pooled 1) is a valid answer nowadays (2016). –MattBianco Sep 26 at 14:43 add a comment| 2 Answers 2 active oldest votes up vote 17 down vote accepted In case someone else runs into this. This is a bug in mod_proxy that can be avoided by putting these lines in your httpd.conf: SetEnv force-proxy-request-1.0 1 SetEnv proxy-nokeepalive 1 https://issues.apache.org/bugzilla/show_bug.cgi?id=37770 For info on what these variables do see the mod_proxy documentat
Post #1 of 5 (6334 views) Permalink reverse proxy via mod_proxy returns HTTP 500 error Hi, I'm trying to configure reverse proxy rules in vhost.conf. I have Apache-2.2.8 on Ubuntu-8.04 (monitored by Plesk-10.4.4). What I'm trying to achieve is defining a reverse proxy rule that defers all traffic to -say- to the Tomcat server running on port 8080. I have mod_rewrite and mod_proxy loaded in Apache. As far as I understand mod_proxy docs, entering following rules in a vhost.conf file should work: | Order deny,allow Allow from all | | ProxyRequests off RewriteRule ^/tomcat/(.*)$ http://mydomain:8080/$1 [P] | (Note: I tested with a RewriteRule directive to get at least some logging.) Yet, I am getting a HTTP 500: internal server error when requesting above URL. I have made mod_rewrite log extensively, and find following entries in the logs: 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (2) init rewrite engine with requested uri /tomcat/testApp/ 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (3) applying pattern '^/tomcat/(.*)$' to uri '/tomcat/testApp/' 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (2) rewrite '/tomcat/testApp/' -> 'http://mydomain:8080/testApp/' 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (2) forcing proxy-throughput with http://mydomain:8080/testApp/ 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (1) go-ahead with proxy request proxy:http://mydomain:8080/testApp/ [OK] This suggests that the rewrite and proxy part are processed ok; still the proxied request produces a 500 error. Addressing the testApp directly via does work, and the same setup does work on my local computer. Does anyone have an idea what might be wrong, or how I at least can get more useful information than 'internal server error' (apart from above rewrite logs, I can't find any trace of this request in other logs). Any pointers much appreciated! Ron serge.fonv
