Doc Text:
In JBoss Enterprise Web Server, <literal>ProxyErrorOverride On</literal> does not work when used with the mod_proxy_ajp module. When accessing a 404 URL in the <filename>/app</filename> context, a 404 page is displayed from the back end servers such as Tomcat, JBoss Enterprise Application Platform, etc. This is fixed in JBoss Enterprise Web Server 2.1 and works as expected.

Description Masafumi Miura 2013-07-12 16:59:59 EDT
Description of problem:

* "ProxyErrorOverride On" does not work if used with mod_proxy_ajp module. When I access a 404 URL in the /app context, which is proxied with AJP, I get a 404 page from backend servers (Tomcat, JBoss EAP, and so on). 
* Accessing 404 URLs via non-proxied content works as intended, as defined in "ErrorDocument". 
* It works in mod_proxy_http (i.e. changing protocol to ajp to http).

[ Config Snippet ]
ProxyPass /app/  ajp://
ProxyErrorOverride On
ErrorDocument 404  /error/404.html

Version-Release number of selected component:

* JBoss EWS 2.0.1 (httpd-2.2.22)

How reproducible:


Steps to Reproduce:

1. Define "ErrorDocument" and enable "ProxyErrorOverride" on mod_proxy_ajp setting. For example:

    ProxyPass /app/  ajp://
    ProxyErrorOverride On
    ErrorDocument 404  /error/404.html

2. Access a 404 URL via definied "ProxyPass" context

    curl -v http://localhost/app/foobar

Actual results:

* 404 error from backend (proxied) server.

Expected results:

* 404 error as defined in "ErrorDocument" via Apache httpd.

Additional info:

* There is an Apache BZ https://issues.apache.org/bugzilla/show_bug.cgi?id=50945 and a fix http://svn.apache.org/viewvc?view=revision&revision=1087864 for this issue in upstream.
* There is a Red Hat BZ#694939 for Apache httpd in RHEL 6. And it has been fixed in Apache httpd rpm package httpd-2.2.15-15 included in RHEL 6.2.
