Re: 400 error code when sending same POST request again

Tue, 05 Sep 2006 09:16:27 -0700

I did a quick search for the problem to refresh my memory.

a) if you get this error, it's a local error, not a server error (if the server closed the connection, .NET would state "aborted by the server" instead of "host"

b) most likely it's an issue with .NET 2.0 and keep alive and HTTP 1.1 . See:

- http://www.msnewsgroups.net/group/microsoft.public.dotnet.languages.csharp/topic26184.aspx

and

http://www.msnewsgroups.net/group/microsoft.public.dotnet.languages.csharp/topic26184.aspx

c) you can work around this by doing excatly what is suggested there (try catch retry...) i  implemented something like this  for C#  as well, as internet connections are prone to break once in a while anyway

d) but, still, most likely is that you are still loosing resources. If NOTHING get's send, then i am pretty confident in at least suggesting to you to investigate for more leaks. .NET 2.0 is a lot less forgiving in that regard than 1.1. was, if you leave a socket hanging somewhere, it is really going to prevent that application from communicating any further.

Sorry that i can not be of more help right now..

I think you are correct however strange this is not an issue in the
compact framework.

I was able to execute the code once after i added some garbage
collection and received the 400 error in return however i did not have
fiddler running (figures)

Now even though i have appropriate garbage collection in place I am
still getting a :

System.IO.IOException was unhandled
  Message="Unable to write data to the transport connection: An
established connection was aborted by the software in your host
machine."

could this be because i still have a pending request on the google
server? How long does the request stay current on the server before
timing out? I feel like I am almost there..... just need that last
push.

thanks again for all the help
