http://issues.apache.org/bugzilla/show_bug.cgi?id=39588 Summary: Mod_Proxy_Balancer with Mod_Rewrite intermittently connects to incorrect host Product: Apache httpd-2 Version: 2.2.2 Platform: Sun OS/Version: other Status: NEW Severity: normal Priority: P1 Component: mod_proxy_balancer AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] CC: [EMAIL PROTECTED] The software is version 2.2.2 (prefork) built with GCC 3.4.2, compilation commands and loaded modules are listed below. We're using mod_rewrite, mod_proxy, and mod_proxy_balancer to distribute requests for a website between 2 Zope instances for local content, and a third-party content provider. The problem occurs intermittently, where requests that should be proxied to a Zope instance running locally on the server are being submitted to the third party content provider, like this configuration snippet: RewriteRule ^/(yyyyyyyyy.*)$ http://content.provider.net/$1 [P,L] RewriteRule ^/(zzzzzzzzz.*)$ http://content.provider.net/$1 [P,L] RewriteRule ^/static(.*)$ /static$1 [L] RewriteRule ^/(.*)$ balancer://zopecluster/VirtualHostBase/http/websites.domain.tld:80/www_site/VirtualHostRoot/$1 [P,L] <Proxy balancer://zopecluster> BalancerMember http://localhost:9080 BalancerMember http://localhost:9081 #BalancerMember http://localhost:9082 #BalancerMember http://localhost:9083 </Proxy> We upped the logging on the servers and extracted the following: access_log: website.domain.tld - - [12/May/2006:17:23:03 -0800] "GET /outages_and_maintenance?[object%20Object] HTTP/1.1" 404 346 error_log: [Fri May 12 17:23:03 2006] [debug] mod_proxy_balancer.c(41): proxy: BALANCER: canonicalising URL //zopecluster/VirtualHostBase/http/website.domain.tld:80/www_site/VirtualHostRoot/outages_and_maintenance [Fri May 12 17:23:03 2006] [debug] mod_proxy_balancer.c(803): proxy: Entering byrequests for BALANCER (balancer://zopecluster) [Fri May 12 17:23:03 2006] [debug] mod_proxy_balancer.c(396): proxy: BALANCER (balancer://zopecluster) worker (http://localhost:9081) rewritten to http://localhost:9081/VirtualHostBase/http/website.domain.tld:80/www_site/VirtualHostRoot/outages_and_maintenance?[object%20Object] [Fri May 12 17:23:03 2006] [debug] mod_proxy.c(736): Running scheme balancer handler (attempt 0) [Fri May 12 17:23:03 2006] [debug] mod_proxy_http.c(1661): proxy: HTTP: serving URL http://localhost:9081/VirtualHostBase/http/website.domain.tld:80/www_site/VirtualHostRoot/outages_and_maintenance?[object%20Object] >>> [Fri May 12 17:23:03 2006] [debug] proxy_util.c(1811): proxy: connecting http://localhost:9081/VirtualHostBase/http/website.domain.tld:80/www_site/VirtualHostRoot/outages_and_maintenance?[object%20Object] to localhost:9081 [Fri May 12 17:23:03 2006] [debug] proxy_util.c(1911): proxy: connected /VirtualHostBase/http/website.domain.tld:80/www_site/VirtualHostRoot/outages_and_maintenance?[object%20Object] to content.provider.net:80 <<<< [Fri May 12 17:23:03 2006] [debug] proxy_util.c(2005): proxy: HTTP: fam 2 socket created to connect to localhost [Fri May 12 17:23:03 2006] [debug] proxy_util.c(2101): proxy: HTTP: connection complete to 64.8.70.102:80 (content.provider.net) [Fri May 12 17:23:03 2006] [debug] mod_proxy_http.c(1443): proxy: start body send [Fri May 12 17:23:03 2006] [debug] mod_headers.c(612): headers: ap_headers_output_filter() [Fri May 12 17:23:03 2006] [debug] mod_proxy_http.c(1530): proxy: end body send [Fri May 12 17:23:03 2006] [debug] proxy_util.c(1769): proxy: HTTP: has released connection for (*) The 404 return is coming from the third-party servers - this has been verified with packet traces running for incoming traffic and outgoing. This behavior appears to be similar to PR 39253 - we upgraded to 2.2.2 in an attempt to correct this behavior noting that this bug had been fixed. My appologies if I should have re-opened that bug vs. opening a new report - this is my first, please be gentle! Thanks again for your time! Ray D.
