Sorry for the technical nature of this message.

With the help of a fellow user with an iPaq (Larry H) I have figured out WHY
the Axim cannot visit certain sites with PocketIE. The reason is the
following line sent by pocket IE in the initial "GET" packet:

UA-CPU: Intel® PXA250

The reason for the problem is the ® character. If that character is present
certain web servers will return with the bad request error. I have narrowed
it down to this character by writing a custom app that sends a GET packet to
http://wireless.cnn.com with custom headers. If the ® is present a "Bad
request" is received, if the ® is ommited the server returns the correct
page.

So far the servers that have a problem with the ® symbol have identified
themselves as: Server: Netscape-Enterprise/4.1. I have only checked a
couple sites so I don't know whether the problem is with all instances of
this specific server, nor whether it is limited to servers of that type.

FWIW the packet sniffer I use (EtherReal) ALSO doesn't like GET packets with
a field that contains the ®, so perhaps IE is violating the standard for
http GET requests? I don't know.

Now with the problem narrowed down the question is HOW to remedy it. So far
I haven't figured out how to get PocketIE to modify the UA-CPU line it
sends. I plan to look through the registry, but I doubt that line is
variable, chances are it's hard coded at compile time by Microsoft, in which
case it's up to them to fix it, and for Dell to pass it on.

The interesting thing is do other PDAs based on the Intel PXA250 send the
same header string?

Anyways if anyone out there has any further questions please let me know,
let's hope Microsoft is listening. TTYL

Terrific sleuthing job! I hope the "powers that be" get wind of this. . .

It's critical that we get this into the right hands @ dell... I posted again
to Rollie on the dell message boards...

Kudos again to you repatch...

Thanks repatch for your efforts into this!

I just wanted you to know that I have posted your message - All credit to
you of course - onto a forum www.aximusers.com . Lots of folks on that forum
were wondering about the message, including me.

Hopefully Dell can figure a fix and get it to us!
