HttpRequest (well known by now..) error

[objectref]

Hi,

does anybody have found a working solution for this HttpRequest error :
"ServerProtocolViolation/The server committed a protocol violation.
Section=ResponseStatusLine"

i tried the solution regarding the app.config file, by puting there the
following

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.net>
<settings>
<httpWebRequest useUnsafeHeaderParsing = "true" />
</settings>
</system.net>
</configuration>

on the client (and the server that is runnign an http server software)
but i keep getting the same message...


Thanks a lot for any help

The documentation for the UseUnsafeHeaderParsing property on the
HttpWebRequestElement states the following:

Header names cannot have non-ASCII chars in them. This validation is
performed whether this property is set to true or false.

I'm assuming that this is the problem that you are facing. It's really
an error on the server's part, and that is the area where it should be
fixed.

You might have to resort to parsing the headers/etc, etc yourself.
Either that, or use another third party provider (perhaps IP works).

Hope this helps.

Thanks for the reply!

I initialize a stream writer on the server part to write something on the
socet that took the http request.
You mean that is something there that is not correct ?


Thanks again..

Yes, that is probably what is happening.

I some time ago I needed to connect to a web service that returned no
headers at all, just the content. I ended up writing a HTTP request
directly to a tcp connection and reading the results. The
HttpRequest/Response classes in .Net are *very* strict when it comes to
the actual protocol.

You should not that the HTTP protocol is quite complex. The easiest
solution is to host your application in IIS as an ASP.net application so
that it can offload all the protocol stuff from you. But if that is not
possible, then have a look at the System.Net.HttpListener class instead
of rolling your own solution on the server side.

Kind regards,

Hey Jesse,

thanks for the help!

The funny thing is that the app is relatevely simple and it is
a clasic windows applicatio.
Socket opens, send data and receive data, just like you describe.
