Hi

      Yesterday I had the same problem, but found my code contains 
redirection https. When the browser option dont have support to 
request a https (a secured socket http), you will get this kind of problem. in IE go 
to tools -> internet option-> and look for advanced tab then move to Security and look 
for SSLc option should be checked.

Hello,

I've been working on this rather unusual, but extremely frustrating problem
for a couple weeks now.

What happens is that people go to visit a site in Internet Explorer, and
they navigate around the site a bit and then get a "Server not found or DNS
error".  When this error appears, it is usually resolved by hitting the
"Refresh" button in the web browser (sometimes it's necessary to visit
another site, then type go back to the problem site).  I've tried visiting
the troublesome sites in Mozilla, which seems to exhibit the same behavior,
but rather than displaying an error, it just stays on the current page; when
this happens, simply clicking the link again usually resolves the problem.

I've tried accessing the problematic websites from numerous different
computers and ISPs, all with the same type of errors. You can imagine my
clients concern when it appears that their site is not available to
visitors.  You can see the problem at two sites: firstchair.com and
vtspiceoflife.com--simply by clicking on different links around the site.
The problem does not appear to be linked to a particular network, as
firstchair.com is connected to a completely different T1 line (and ISP, for
that matter) than vtspiceoflife.com.  Sometimes it doesn't happen for 50
clicks or more, other times the site will not even show on the first
request.  Nothing shows in any of the system or Apache error logs.

The problem seems to appear when I'm working with PHP scripts, but I've
never seen it working with non-script sites.

I have been running Apache (The problem has occurred with 2.0.48 and
1.3.29), PHP (4.3.4 and 4.3.3) and MySQL (in some cases on a separate
server, other times on the same system--tried both the PHP-packaged MySQL
client and the client compiled from MySQL source).  I've been building with
libmm (tried both 1.3.0 and 1.1.3, compiled from source and alternatively
the distro-included package), sometimes using SSL (compiled from source and
also the distribution-included binary), but never using compressed delivery.
In all cases MySQL, PHP and Apache were built from source.

I've been primarily using Slackware 9.1, but yesterday tried FreeBSD 4.9
only to find the same errors.  I have build on a variety of hardware;
different motherboards, Pentium 4 CPUs and AMD Athlon XP CPUs.  I have used
different memory brands and sizes, in different arrangements ranging from
256 MB to 1024MB.  I've used different network cards including both the
integrated motherboard adapters as well as PCI expansion card adapters.

I've searched the Internet for quite some time with no success, but I really
hope the problem is something obvious.  I had previously built systems
almost identical to these with great success.  As I'm sure you can imagine,
I'm on my edge with this, and I have a tremendous amount of pressure to find
a solution ASAP.

Thank you very much for you time and ideas,

John Holden
