As a test, can you try using regsub instead of string map?

 

 

http://www.tcl.tk/man/tcl8.4/TclCmd/regsub.htm

 

 

Also, you can simplify the collection size logic a bit and make sure you avoid collecting more than 1Mb of payload by modifying your HTTP_RESPONSE code:

 

 


when HTTP_RESPONSE {
   if {[HTTP::header value Content-Type] contains "text"} {
      if { [HTTP::header exists "Content-Length"] and [HTTP::header "Content-Length"] < 1048575 } {
         set content_length [HTTP::header "Content-Length"]
      } else {
         set content_length 1048576
      }
      if { $content_length > 0 } {
         HTTP::collect $content_length
      }
   }
}
