large number of redirects

Sure.

Step 1: create a data group (LTM GUI: iRule | Data Group List | Create). Enter a name (example "my_test_dg"), select "String" type, and start entering strings and values. Example:

"/something-else" := "http://our-domain.com/some/other/URI/values"

"/something" := "http://our-domain.com/some/URI/values"

"/and-so-on" := "http://our-domain.com/and/so/on"

** I would order these from most to least specific if the URIs start with the same string values.

Step 2: Create the iRule:

when HTTP_REQUEST {
     if { [class match [string tolower [HTTP::uri]] starts_with my_test_dg] } {
          HTTP::redirect [class match -value [string tolower [HTTP::uri]] starts_with my_test_dg]
     }
}
