How to modify "Cache-Control" header in Drupal 5.x? -

-

we using drupal 5.x. experimenting squid reverse proxy. squid , drupal configured. static content getting cached.

for testing purposes, set "cache-control: public ..." on 'authenticated' pages returned drupal.

we see headers set in bootstap.inc. we've modified instances of "cache-control" header in file, set 'public'. however, when view http headers (in safari's web inspector), see "cache-control:private". reason, squid returning cache miss on pages.

question - "cache-control" getting set "private"? how can change "cache-control" header authenticated users?

thanks in advance!

try pressflow (https://launchpad.net/pressflow/5.x) fork of drupal built in cache control.
