For example, suppose I have a list, list@foo.com. The list information page would appear at:
http://whatever.hostingrails.com/mailman/listinfo/list_foo.com
But I would like it to appear at:
http://foo.com/mailman/listinfo/list_foo.com
I tried an Apache rewrite rule with the Proxy Throughput flag, as suggested in the URL Rewriting Guide (Dynamic Mirror section). Here is the rule I used:
RewriteEngine On
RewriteBase /
RewriteRule ^mailman/(.*)$   http://whatever.hostingrails.com/mailman/$1 [P]
But, the rule doesn't fire, and I get only a blank page. I know the rule is good, because if I change "mailman" (on the left side) to anything else, it works fine. So it seems that there is a higher Apache rule on the server that is intercepting the request to "mailman" URLs.I am fine with using a different word than "mailman", but there is also the trouble that all the links that Mailman generates will use "whatever.hostingrails.com" instead of "foo.com", which defeats the purpose.
Is there some way to make Mailman use the URL I want? Or another way to disguise the URL?
