My organization is changing proxy servers from WAM to EZproxy, and we would like to give staff time to change over their URLs before we make the switch. I would like to set up forwarding so the links using the new proxy get redirected to the old proxy. I'm planning on using apache's mod_rewrite to do this. Basically, this mod rewrite rule needs to do three things: 1) Change the part of the domain name (not the file path) that reads "ezproxy.switchinc.org" to our old domain "topcat.switchinc.org" 2) Append the prefix "0-" in front of the domain name 3) Transform dashes in the domain name to periods. Could anyone provide me with some assistance? I am sure this takes maybe 10 lines of code from a mod_rewrite expert, but it has taken me several weeks to the first two objectives done, and all of my google fu is failing me for objective three. Below is what I have: RewriteEngine on RewriteCond %{HTTP_HOST} ^(.*)ezproxy.switchinc.org [NC] RewriteRule ^(.*) %{HTTP_HOST}/$1 [DPI] RewriteRule ^(.*)ezproxy.switchinc.org/(.*) http://0-$1topcat.switchinc.org/$3 [L] Thanks, Karl Holten Systems Integration Specialist SWITCH Inc 414-382-6711
