Debugging your Proxy Configuration
The above is a simple case taken from mod_proxy_html version 1. With
the more complex URLmapping and rewriting enabled by Version 2, you
may need a bit of help setting up a complex ruleset, perhaps involving
a series of complex regexps, chained anc blocking rules, etc. To help
with setting up and troubleshooting your rulesets, mod_proxy_html 2
provides a "debug" mode, in which all the 'interesting' things it does
are written to the Apache error log. To analyse and fix your rulesets,
set
ProxyHTMLLogVerbose On
LogLevel Info (or LogLevel Debug)
Now run your testcases through your rulesets, and examine the apache
error log for details of exactly how it was processed.
Do not leave ProxyHTMLLogVerbose On for normal use. Although the
effect is marginal, it is an overhead.
