Getting HTTP_Headers When Writing Module

Hi all,

Does anyone know how to use the "table" structure, defined as part of the Apache API for MOD authors?

They provide 'ap_table_get( table, key )' but I don't know the values it's expecting for "key". It would be easier to just walk through the table spitting out the key/value pairs so that I can see what it's expecting but I can't see a way to do this.

Any help would be appreciated.

I'm aware this site is mainly for Apache config (system admin) issues so if anyone knows a good forum for APACHE mod authors that would also be really useful.

Regards,

Karl
