Hi,

This seems to work - wondered if anyone could comment on it's sanity:

RewriteEngine on
RewriteRule                 "^/wibble/(.*)$" "/$1"
RewriteRule                 "^(/_a/.*)$"    "$1"                       [PT]
RewriteRule                 "^/(.*)$"  "http://localhost:8180/wibble/$1" [P]
ProxyPassReverse            /          http://localhost:8180/wibble/
ProxyPassReverseCookiePath /wibble      /

This is to do with fronting a tomcat webapp /wibble on port 8180 with 
apache.

The logic is:

* Knock any /wibble prefix off the URL ('cos the tomcat is rooted there)
* (reverse) Proxy everything to localhost:8180/wibble/$1 EXCEPT
* anything beginning _a should be handled by regular filemap by apache 
(static content)

* Fix any redirects etc coming from the server towards the client.

I tried a ProxyPass - but it seems to take precendence over the rewrites. I 
added a Proxy ... ! directive, but it all got rather messy mixing them.

I guess, the real question is:

Is "ProxyPass blah BLAH" identical to
RewriteRule ^blah/(.*)$ /BLAH/$1 [P]

or are there some subtle differences I might get caught by?

RTFM, seems to be the case (rewrite ...[P] uses mod_proxy) but just checking 
as I will be using the recipe on many servers in due course.

TIA :)

Tim
