[users@httpd] proxypass ignore case issue
I have a server setup as a reverse proxy for a server called for example
www.somedomain.com
If a user goes to http://www.somedomain.com/somedir, I want it to goto
http://appserver.blah.com/somedir
I have the following
<LocationMatch "/somedir">
ProxyPass http://appserver.blah.com/somedir
ProxyPassReverse http://appserver.blah.com/somedir
</LocationMatch>
The above works great. The problem is, that is does not match
http://www.somedomain.com/Somedir or /SoMeDir etc etc...
I want it to ignore case. Is there a way to do this easily with using
mod_rewrite?
I am running
Server version: Apache/2.0.52
Server built: Aug 2 2006 05:21:10
with Mod_proxy

This is complex enough that it is best dealt with in mod_rewrite:
RewriteEngine On
RewriteRule /somedir(.*) http://www.somedomain.com/somedir$1 [P,L]
RewriteRule /somedir(.*) http://%{SERVER_NAME}/somedir$1 [NC,R,L]
RewriteRule (.*) http://www.somedomain.com$1 [P,L]
ProxyPassReverse ...

In my case the backend host is a IIS server. Any ideas?

that's out of sync, try
proxypass / http://www.somedomain.com
proxypassreverse / http://www.somedomain.com
(both lines after all other proxypass/proxypassreverse lines)

Simply activate mod_speling on the backend host, too. The redirect
coming from the backend host gets rewritten by the proxy host exactly
as needed due to the proxypassreverse directive, thus it is important
that the parameters of proxypass and proxypassreverse are identical.

Re: [users@httpd] proxypass ignore case issue

Thanks Rainer.
The mod_speling works great. However I have a new interesting problem
In my vhost I have
proxypass /somedir /http://www.somedomain.com/somedir
proxypassreverse /somedir /http://www.somedomain.com/somedir
The above works fine and mod_speling catches any weird way that somedir
can be written.
But...
Since I need this server to also proxy requests to / for
www.somedomain.com when I put in
proxypass / http://www.somedomain.com
proxypassreverse / /http://www.somedomain.com/somedir
the mod_speling no longer works. It seems to only process only if none
of the proxypass rules match
and since the rule for / matches http://www.somedomain.com/SoMeDir
mod_speling does not kick in.
Do you know of a way around this?
Thanks,
Nick

correct.

When a user goes to <http://www.somedomain.com/SoMeDir> there is no
need for a reverse proxy. mod_speling returns a Redirect because it
finds the local dummy directory "somedir" in the local "htdocs"
directory.
When the browser follows the redirect, i.e. when it sends a new request
to <http://www.somedomain.com/somedir>, your existent reverse proxy
configuration entry is regarded, thus the server does not even look
at/into the dummy directory now.
I.e. the server will never serve any contents of the dummy directory.
(It does not even matter whether "somedir" is a directory or a file or
a symlink or something else: only the pure entry of the name in the
htdocs directory is regarded by mod_speling. I myself use "ln -sf
Redirect .../htdocs/somedir" to create a dangling symbolic link for
this purpose.)

With mod_speling, that only appears to work if the directory is on the
local machine? What about in the case of a reverse proxy?

I prefer mod_speling using a dummy directory:
mkdir /path/to/htdocs/somedir
When the browser requests <http://www.somedomain.com/SoMeDir>, mod_speling
returns a redirect to <http://www.somedomain.com/somedir>. Voilà!
