Search and replace a field in HTTP Header

Hi,

 

 

If you want to perform a replacement with dynamically generated strings, I think you'd need to collect the request data and use regsub and a backreference to replace the matched content with the string set to lowercase. If the replacement strings are the same length as the existing strings, you can use the credit card scrubber rule (Click here) as an example for how to collect the data and replace the strings.

 

 

Does anyone know if it would be possible to manipulate the payload with a binary scan and a simpler string map + string tolower combination instead?
