Command ordering with stream profile

Hi all,

Does anyone have any explanations as to why the order of commands matters here?

Using the HTTP_RESPONSE event below:

  
 when HTTP_REQUEST {  
  
      save original hostname and place it in xHost header  
      set orighost [HTTP::host]  
      HTTP::header insert "xHost" $orighost  
  
       see if vchannel was requested (ie, last char of hostname is v, ignoring the .example.com)   
       set boxname [string tolower [getfield [HTTP::host] "." 1]]  
         if { $boxname ends_with "v" } {  
               set channel "v" 
            } else {  
               set channel ""  
            }  
  
        build the new Host header and $WSSN header  
        HTTP::header replace "Host" rwa$channel.example.com  
        HTTP::header replace "\$WSSN" rwa$channel.example.com  
  
    make sure all cookies use wildcard of .example.com as their domain  
    foreach N [HTTP::cookie names] {  
       HTTP::cookie domain $N .example.com  
    }  
  }  
  
  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 any instance of rw*.example.com with original Host header  
      STREAM::expression "@rw.*?.example.com@$orighost@"  
  
         Enable the stream filter for this response only  
        STREAM::enable  
     }  
  
  make sure all cookies use wildcard of .example.com as their domain 
    foreach N [HTTP::cookie names] {   
     HTTP::cookie domain $N .example.com 
    }  
  }  
 

The page stalls and never loads. No errors are thrown in /var/log/ltm either.

But if the order is changed to:

  
 when HTTP_RESPONSE { 
  
  make sure all cookies use wildcard of .example.com as their domain    
   foreach N [HTTP::cookie names] {   
    HTTP::cookie domain $N .example.com    
   }  
  
   Disable the stream filter by default  
     STREAM::disable  
  
      Check if response type is text  
     if {[HTTP::header value Content-Type] contains "text"}{  
  
         Replace any instance of rw*.example.com with original Host header  
      STREAM::expression "@rw.*?.example.com@$orighost@"  
  
         Enable the stream filter for this response only  
        STREAM::enable  
     }  
 }  
 

Then the page loads normally. Should stream operations always come last in an event? Thoughts?
