hello list,

I'm very sorry to jump straight in here with a question, but here  

goes:

I've got a fairly normaly thin-and-thick setup with a mod_perl server
in the background. The thin server on 80 is a reverse proxy for the
mod_perl server on 8081, in the usual way. The only quirk is that for
some directories I'm forcing secure access and bypassing the proxy:
those I redirect to the same mod_perl server, but on port 443.

It all works very nicely except for one thing:

* url with query string proxied to the non-secure port on the
mod_perl server works fine
* url with qs redirected to the secure port on the same server
arrives without the query string

There's quite a big stack of handlers on the mod_perl server,
including a TransHandler, so at first I just assumed I was breaking
the input, but I'm really not: I've been able to make sure that the
request really does come in without the query string.

As it happens this application will accept similar input in the
path_info so I can get by for the few cases where the redirect kicks
in. But I thought mod_alias just ignored the query string? please

could someone suggest why they're getting eaten? It's driving me  

nuts.

There seems to be a rash of people today posting semi-complicated
URL-mapping problems who describe the problem but neglect to show the
configuration they are using or any concrete examples of what is
happening.  This makes solving the problem almost impossible.

I'm sorry. Here's my semi-complicated host configuration:

<VirtualHost *:80>
	DocumentRoot /home/foo/public_html
	ServerAdmin sysadmin@xxxxxxxxxxx

	ServerName www.foo.org
	ServerAlias foo.org

	DirectoryIndex index.shtml index.html index.htm

	ProxyRequests Off
	ProxyPass / http://www.foo.org:8081/
	ProxyPassReverse / http://www.foo.org:8081/

	CacheRoot /home/foo/html_cache
	CacheSize 5000
	CacheGcInterval 1
	CacheMaxExpire 2
	CacheLastModifiedFactor 0.1
	ProxyReceiveBufferSize 49152

	<Location "/">
		Redirect permanent /admin https://www.foo.org/admin
		# and a few others the same
	</Location>

	CustomLog /home/foo/logs/access_log combined
	ErrorLog /home/foo/logs/error_log
</VirtualHost>

This is 1.3.27 (oops), compiled with suexec, mod_alias, mod_rewrite  

and mod_include, and iirc nothing else.

Thanks,

will

Joshua.
