filter out a header entry

[Michael Renner <michael.renner@xxxxxx>]

Moin,

I have to filter a out a 'non standard' http header that I set with the 
firefox plugin 'modify header': UseSquidProxy: true'.

I found that only 'standard' headers can be processed by  header_access, so I 
set
                header_access Allow allow all
                header_access Authorization allow all
                header_access WWW-Authenticate allow all
                header_access Proxy-Authorization allow all
                header_access Proxy-Authenticate allow all
                header_access Cache-Control allow all
                header_access Content-Encoding allow all
                header_access Content-Length allow all
                header_access Content-Type allow all
                header_access Date allow all
                header_access Expires allow all
                header_access Host allow all
                header_access If-Modified-Since allow all
                header_access Last-Modified allow all
                header_access Location allow all
                header_access Pragma allow all
                header_access Accept allow all
                header_access Accept-Charset allow all
                header_access Accept-Encoding allow all
                header_access Accept-Language allow all
                header_access Content-Language allow all
                header_access Mime-Version allow all
                header_access Retry-After allow all
                header_access Title allow all
                header_access Connection allow all
                header_access Proxy-Connection allow all
                header_access All deny all
to deny anything else. But without success. By special header as well as 
User-Agent is passed to the webserver.
Where ist my error in reasoning?

Thanks for any hint!
