Remove HTML comments

In case you hadn't gotten to it yet, here's a bit of code that should get you rolling:

 

 

when HTTP_REQUEST {
   Don't allow data to be chunked
  if { [HTTP::version] eq "1.1" } {
    if { [HTTP::header is_keepalive] } {
      HTTP::header replace "Connection" "Keep-Alive"
    }
     HTTP::version "1.0"
  }
}
when HTTP_RESPONSE {
  if { [HTTP::header exists "Content-Length"] } {
     set content_length [HTTP::header "Content-Length"]
  } else {
     set content_length 1000000
  }
  if { $content_length > 0 } {
     HTTP::collect $content_length
  }
}
when HTTP_RESPONSE_DATA {
   Find the HTML comments
  set indices [regexp -all -inline -indices {} [HTTP::payload]]
   Replace the comments with spaces in the response
  log local0. "Indices: $indices"
  foreach idx $indices {
     set start [lindex $idx 0]
     set len [expr {[lindex $idx 1] - $start + 1}]
     log local0. "Start: $start, Len: $len"
     HTTP::payload replace $start $len [string repeat " " $len]
  }
}

 

 

I modified the SSN scrubber on CodeShare. If anyone sees any problems with the HTML Comment regex, please let me know!

Cool. It doesn't get some odd ball cases like , but I think it should work for most situations.
