Proxypass with page content modification?

I did this once before but can't find the exact rule. If I remember correctly, using HTTP::header replace Accept "" doesn't actually replace the value of the header. I ended up using something like this:

  
  when HTTP_REQUEST {  
    
     HTTP::header replace Accept-Encoding [list ""]  
  }  
  when HTTP_REQUEST priority 501 {  
     log local0. "\[HTTP::header value Accept-Encoding\]: [HTTP::header value Accept-Encoding]"  
  }  
  

If that doesn't null the value of the Accept-Encoding header, can you try this:

  
  when HTTP_REQUEST {  
    
     HTTP::header replace Accept-Encoding [list {}]  
  }  
  when HTTP_REQUEST priority 501 {  
     log local0. "\[HTTP::header value Accept-Encoding\]: [HTTP::header value Accept-Encoding]"  
  }  
  

Once you're done testing, you can remove the HTTP_REQUEST 501 event as it's just there for debugging. You could use this as a separate rule or add it into your full proxypass rule.
