**Also posted in inetserver.iis newsgroup as I am unsure of where the
problem lies**
Hi,
I have a strange problem, or I may just be stupid, but wondering if anyone
can help with this one:
We receive a large number of very simple POST requests to our vb.net web
apps from our suppliers (all using php or jsp - if that has any relevance).
Historically our ,net apps have been hosted (still are!) on win2k boxes with
IIS5 with no problem, GET and POST requests work fine, from their apps,
IE5/6 ... all fine!
Now here is where the problem starts, recently put two new servers (2003 std
with IIS6) in our colo, installed the same apps, and they appear to work
fine (make GET requests from IE6 - fine) however our clients get a 500 error
when posting and when simulating a session through telnet the server
responds with 500.
All i can see in the logs is the request coming in as a POST with 500 as the
error code.
Any help much appreciated (if you need more info please let me know)
Many thanks in advance 11 2334

In IE6, turn 'Show friendly error pages' on and off and find out if it
makes any difference. Don't know exactly what the case is but that's
what I've found ou once.

Hi,
thanks for your thoughts, unfortunatly each time i connect to the page from
IE (Show friendly error pages on or off) it displays perfectaly. The only
way I can replicate the problem locally is to set up a manual telnet session
to the server

What request do you eumlate via telnet to reproduce the error?
Cheers,

Hi Joerg,
the sample app I am using is a test one, so it can accept any parameters
and just logs the details of the request into a text file.
I am not too sure what you mean by 'What request do you eumlate via telnet
to reproduce the error?' but I will give you a full list of what I do when i
telnet it!
telnet xxx.xxx.xxx.xxx 80
POST /appname/page.aspx HTTP/1.0
Host: xxx.xxx.xxx.xxx
Content-type: application/x-www-form-urlencoded
Content-length: 9
test=true
If there is any other way of testing please let me know - also is there a
telnet app that you can see the local echo?
Thanks in advance

Yeah, that's I meant. You're pretending to be a web client by typing in HTTP
requests via telnet :-)
telnet xxx.xxx.xxx.xxx 80 POST /appname/page.aspx HTTP/1.0
Wait. There must be no empty line here, othwerwise your headers become the
message body.
Host: xxx.xxx.xxx.xxx Content-type: application/x-www-form-urlencoded Content-length: 9
test=true
You could perform another quick test here. Since you already pass a Host
header, you can safely change the protocol version to HTTP 1.1.
If there is any other way of testing please let me know - also is there a telnet app that you can see the local echo?
You could create a test web form or build a test windows app. As far as the
local echo goes, I'd thought that any old telnet client can do that?
Cheers,

Hi again!
firstly thanks for all your help, with that change to the telnet session you
mentioned it works perfectly with both HTTP1.0 and 1.1.....so i am totally
confused!!

Where do these POST requests from your third parties actually fail? Are they
rejected by IIS 6 right away, or do they cause an exception within the
ASP.NET pipeline?
Cheers,

Rejected before ASP gets hold of them (I think - although I am still
checking) I have a whole load of debug code running in the .net and nothing
seems to get there

I woudl start by trapping errors (using either customErrors tags or
Application_OnE rror). You can then mail this error so that you are aware of
waht's happening in your app without having to reproduce the problem...

Greets,
Part of the content of one of our web pages uses wingdings and Chr(239)
through Chr(242) (which are little arrow outlines, though that's not really
important.)
It worked just fine in Windows 2000 Server, but now under Server 2003 it
seems that characters above 127 get converted somehow, and our code no
longer produces the desired effect.

They couldn't get the server working again so they transferred our site

That was a week ago.
Since that transfer, all of our ASPX pages that use Access2000 databases
