   I'm having trouble with a proxy server caching pages. Is there a 
header or something that I can send to alleviate this problem?

What I have is an htaccess rewrite rule

RewriteRule ^(.*/protected_directory/.*)	/pass_check_script.php?path=/$1

  that sends all requests for a directory to a php script that does some 
password checking and then reads the file and prints a Content-type and 
then prints the file contents. A proxy server has cached the results and 
avoids the pass check.

   I was thinking of sending something in the header, or perhaps just 
amending some random string to the html. I know proxy servers ignore 
html type no-cache settings.
