How to remove mixed content for https site

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 
    } 
 }
