Appending iRule

If you just want to rewrite requests to the root document (path equals /), you could use this:

  
 when HTTP_REQUEST {  
     Check if path is /  
    if {[HTTP::path] eq "/"}{  
  
        Rewrite path to /test/app.aspx 
       HTTP::path "/test/app.aspx"  
    }  
 }  
 

If you want to prepend a string to all URIs if it's not there already, you can use a rule like this:

  
 when HTTP_REQUEST {  
     Check if path doesn't already start with /test/ 
    if { not ([HTTP::path] starts_with "/test/")}{  
  
        Rewrite path by prepending "/test/" 
       HTTP::path "/test/[HTTP::path]"  
    }  
 }  
 

Note that if you don't care about inspecting the query string it should be more efficient to modify just the path using HTTP::path.
