iRule to change a take a URL and add URI then send to a Pool.

Hi Everyone,

I have a simple pool selection iRule in place for some internal sites but have been asked to have a URI added at the end to make it easier for people to access. I currently have: 

when HTTP_REQUEST {
      switch [string tolower [HTTP::host]] {
        "sharepoint.test-site.com" {
          pool /Internal/F5-Internal-Pool_sharepoint
        }
        default {
          discard
        }
      }
    }

and I would like merge it with something along the lines of : 

when HTTP_REQUEST {
        if { [string tolower [HTTP::uri]] equals "/" } {
        HTTP::redirect "https://[HTTP::host]/Pages/default.aspx"
    }

}

How would I merge these two together?

    Try this one:

        when HTTP_REQUEST {
      switch [string tolower [HTTP::host]] {
        "sharepoint.test-site.com" {
          if { [HTTP::uri] equals "/" } {
           HTTP::redirect "https://[HTTP::host]/Pages/default.aspx"
          }
          else {
           pool /Internal/F5-Internal-Pool_sharepoint
          }
        }
        default {
          discard
        }
      }
    }

    Any performance impact using if with switch? I just started with iRules and in the 101 they mention how its better to use switch rather than if.

    I don't think you'll encounter any performance issues with the if inside of the switch. Plus it gives you additional flexibility down the road if you want to expand your iRule.
