ProxyPass problem

It looks like there might be a slight issue with the ProxyPass iRule's use of 'HTTP::header replace'. Can you find this line:

 
          HTTP::header replace Host: $host_serverside 
 

and replace it with this line?

 
          HTTP::header replace Host $host_serverside 
 

and this line:

 
             HTTP::header replace $header: $protocol$host_clientside$path_clientside[substr $server_path [string length $path_serverside]] 
 

with this line:

 
             HTTP::header replace $header $protocol$host_clientside$path_clientside[substr $server_path [string length $path_serverside]] 
 

and then retest?

Thanks,

Aaron
