[users@httpd] Logging an masqueraded header in Apache 2.4

[Christian Georg]

Hi all,


I am looking for a solution to masquerade/anonymize data I am writing to the 
acccess log on my proxy. For debugging purposes we need to trace data based on 
the x-auth header. As this header contains critical data I do not want to 
enable logging of the full header. Instead I am looking for a solution to only 
log the first X and the last y header. so instead of logging


  ycsfsfdawlkcfawncfewmlcsdfacs


I would like to see something like this

  ycsfsfd###############csdfacs

 or this.

  ycsfsfd..csdfacs

I am using apache 2.4 on centos
Any suggestion?

Thanks

Chris
