HTTP Redirect failure

for one thing a huge elseif elseif elseif approach isn't the best way to handle this, please look into a switch statement.

also it is wise to convert the HTTP::uri to lowercase (and also your matching URI) to prevent case issues.

further i only see URI starting with bv2was on the list, so i don't understand which ones worked. but when i go to the URI im redirected to the https site, it might be there is another iRule which does that redirect which conflicts with your maintenance irule.

finally you might want to delete your company name from all those links.
