Looking for iRule to forward based on uri

I have an iRule here:

 

 

 

when HTTP_REQUEST {

 

if {[HTTP::uri] eq "/proposals/webpagenumber1*" } {

 

HTTP::redirect "http://domain2.com/Services_and_Products/sub1/sub2/Proposals/webpage1"

 

}

 

}

 

 

But this isn't working in testing... I have tried using wildcards as shown above and other combinations... but the original page is still being displayed.

 

 

I have 10 different uri (pages) from this domain1.com that needed to be redirected to different uri's on domain2.com.

 

 

Is there a simpler way to do this? using 'switch' command?

 

 

 

Basically, a bunch of these with different pages:

 

 

http://domain1.com/proposals/webpagenumber1.htm

 

to

 

http://domain2.com/Services_and_Products/sub1/sub2/Proposals/webpage1

 

 

Thanks!

    Hi Sean,

     

     

    If the comparisons are all the same (check if [HTTP::uri] starts with the list of URIs), you could put all of the URI patterns in a datagroup. You can then use finndclass (v9) or class search -value (v10) to look up the current URI against the datagroup.

    So after some more playing, I ended up with this, which works fine:

     

     

    when HTTP_REQUEST {

     

    if {[HTTP::uri] eq "/proposals/AccessControl.htm" } {

     

    HTTP::redirect "http://domain2.com/sub1/Construction/Proposals/AccessControl"

     

    }

     

    if {[HTTP::uri] eq "/proposals/Davis.htm" } {

     

    HTTP::redirect "http://domain2.com/sub1/Construction/Proposals/Maintenance"

     

    }

     

    if {[HTTP::uri] eq "/" } {

     

    HTTP::redirect "http://domain2.com/sub1/Construction"

     

    }

     

    }

     

     

    My only remaining question is: Can I use a better 'default' for that last line to go to the 'home' of the site than the "/". If people type in anything other than the domain name, or the "/" they will not get forwarded.

     

     

    Thanks again for the help!

    You can use a switch statement for this as well. It's more efficient as you're not performing all three checks if a prior check was true. 

    
when HTTP_REQUEST {

   switch [HTTP::path] {
      "/proposals/AccessControl.htm" {
         HTTP::redirect "http://domain2.com/sub1/Construction/Proposals/AccessControl"  
      }
      "/proposals/Davis.htm" {
          HTTP::redirect "http://domain2.com/sub1/Construction/Proposals/Maintenance"  
      }
      default {
         HTTP::redirect "http://domain2.com/sub1/Construction"  
      }
   }
}

    If you have a lot more URIs to check for and they're all exact matches, you could add all of them to a string datagroup with a 'string' of the URI and a value which is the redirect URL. You can check the class wiki page for examples:
