Looking for an Easy way. Remove the insecure javascript that points to the

Script to remove

 

 

 

I tried this but it doesn't work

 

when HTTP_REQUEST {

 

set newuri "img/icon.offsite.gif"

 

set newhost "www.law.harvard.edu"

 

if { [HTTP::host] contains "www.google.com" and [HTTP::uri] contains "coop/cse/brand?form=cse-search-box&lang=en"}

 

{

 

HTTP::redirect "http://[HTTP::$newhost][HTTP::$newuri]"

 

}

 

 

}

 

 

thanks

    If you're looking to remove a string from within the HTTP payload itself, then your best bet is the stream profile. You won't be able to just perform a redirect as it doesn't look like you're dealing with host or URI information, really, but with the content being delivered by a server that is in turn pointing you to an insecure location to load some javascript.

     

     

    If you want to strip this out, check out the stream profile and what it can do. There are some great examples here on DevCentral, and it should be able to get you where you need to go in the most efficient manner.

    If you want to replace a string within the request or response payload, you can use a blank stream profile and a STREAM::expression based iRule. Set the string to replace as your string with the regex metacharacters escaped. Make sure to check the STREAM::expression wiki page (Click here) for details. 

     
 when HTTP_RESPONSE { 
  
     Disable the stream filter by default 
    STREAM::disable 
  
     Check if response type is text 
    if {[HTTP::header value Content-Type] contains "text"}{ 
  
        Replace google search form with nothing 
       STREAM::expression {@@@} 
  
        Enable the stream filter for this response only 
       STREAM::enable 
    } 
 }
