Use a fully qualified URL for the rewrite.

 

RewriteRule ^foo$         http://blah.com/foo/ [R]

 

I have a farm and many many rewrites, and this works.

Subject: [users@httpd] mod_rewrite

 



We are currently using apache mod_rewrite to solve the trailing slash
problem which works fine but now we have a different problem. 

We use the following rule:  RewriteRule ^foo$         foo/ [R] 

We have three webservers running behind a load balancer.  On each
webserver there are two virtual hosts running on different ports. 

Vhost 1 = www.unmc.edu running on port 80 
Vhost 2 = www.citymatch.org on port 8009 

Since we are using mod_rewrite to add a trailing slash the following
problem occurs: 

1. The user requests the following url from their webbrowser:
http://www.citymatch.org/Conference2005 

2.  This url is passed to mod_rewrite because it is missing the trialing
slash. 

3.  mod_rewrite returns the url as
http://www.citymatch.org:8009/Conference/ 

4.  Since we are using the [R] and external redirect is used. 

5.  The request gets to the firewall and the fire wall won't allow port
8009 and nor will the loadbalancer. 

I realize I could just open these ports up but that would not make us
secure as we could be and that is always the goal. 

Is there a way to tell mod_rewrite not to add a port to the newly
constructed url or tell it to use just the fully qualified name? 

Is it apache that adds the port number to the url?
