[WebException: The remote server returned an error: (400) Bad Request.] System.Net.HttpWebRequest.GetResponse() +5314029 System.ServiceModel.Channels.HttpChannelRequest.WaitForReply(TimeSpan timeout) +54

  • and which of the bindings are you in fact using?? The BasicHttpBinding or the wsHttpBinding?? Commented Mar 16, 2010 at 17:44

Can you tell us a bit about your setup?

  • what binding do you use?
  • is this the only service method? If not: do the others work?
  • show us the configs on client and server! (everything inside <system.serviceModel> is of interest)

It would appear as if the client times out waiting for the server - this can be because the server takes too long to respond (if you do a lot of data loading); in that case, you need to increase your timeouts on the server and the client

Or you might be sending too large a data packet over the wire - in that case, you might also need to increase the settings for maxReceivedMessageSize et al.

@Pinu: are you trying to upload 5 MB? You have transferMode=StreamRequest, which means your request from the client to the server will be streamed.

If you're transferring 5 MB, it's a good idea to stream - which way do you transfer those bytes??

Hey Marc, I have updated the config file information. We are trying to send 5MB(max). and i have already seet maxreceivedmessagesize=100mb. SO i dont think that should be the problem
Hey Marc, It's throwing that error when i enable transfermode="stream" it is throwing this error. With transfermode=buffer it allows me to send up to 3mb files. I am also using message contract and memory stream to request the memory stream
