Humbly seeking pardon for asking a question which might be perceived as offtopic to some.

This aspiring perl-guru needs to redirect requests for certain directories (with the exception of some subtrees) to a different webserver. Examples will make this clear.

Requests to http://server1/basedirectory should go to http://server2/basedirectory

Likewise we need the following:
http://server1/basedirectory/something -> http://server2/basedirectory/something
etc.

However we need to omit some urls from the rule: http://server1/basedirectory/exceptiondirectory1 and http://server1/basedirectory/exceptiondirectory2 (and their subtrees) should stay on the same server and not get redirected.

We have apache 1.3.26 compiled with both mod_alias and mod_rewrite, and we are currently using a very ugly solution to this problem, the following rule:
RedirectMatch ^/basedirectory/([^e])(.*)$ http://server2/basedirectory
+/$1$2

[download]

This will will match our exception directories and then some extra unwanted stuff too.

What I really want is something like what perl supports. Is there a way to do something like the following:
RedirectMatch ^/basedirectory/(?!exceptiondirectory1|exceptiondirector
+y2)(.*)$ http://server2/basedirectory/$1$2

[download]

Thanks in advance to any who can advise me,

Rohit
