anyway to get past browser cache and find out the truth of what is going on?

[lkrubner@geocities.com]

I've got a site on a hosted virtual server. I'd like to know the truth
of what is going on, but I can't get past my browsers cache. There is
some kind of error in my code that occurs on a given line. When I
comment out that one line, everything else seems to work. When I
uncomment that one line, the browser simply shows what was last on
screen the last time the code was working. That is, if I write

echo "hello";

while the line is commented out, then I change the line to

echo "goodbye";

and I uncomment the line and hit the refresh button on my browser, the
word hello will remain on screen. Neither FireFox nor IE will show me
the truth of what they are seeing, either that be nothing or an error
message.

How to get around that?

Your question is confusing, so I'm not sure if this is what you're
looking for, but to stop the browser from caching the page at all, add
this meta tag:
<meta http-equiv="Pragma" content="no-cache" />

If you have the time: read RFC 2616. It will tell you all about
controlling caching mechanisms :)

Telnet to port 80 and manually type a HTTP request?

This is a serverside group, we have access to the real stuff using
header().

Use a browser without a cache.

In about:config in Firefox there are several cache options ending in "enable"
that would likely disable cacheing entirely if you turned them all off.

Or use one of the many command-line HTTP clients that either don't have cache
support or can have it disabled; wget, curl, Perl LWP etc.

Add to the top of your file :

<?php
header( "Expires: Mon, 26 Jul 1997 05:00:00 GMT" );
header( "Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT" );
header( "Cache-Control: no-store, no-cache, must-revalidate" );
header( "Cache-Control: post-check=0, pre-check=0", false );
header( "Pragma: no-cache" );
?>
