400 Bad Request when trying to send large file to service using basichttp streaming.

Posted By:      Posted Date: September 21, 2010    Points: 0   Category :WCF

Hi All,


I am trying to send the large file (approx 1.5GB) to the WCF service for upload using basic http streaming.

I have increased all the timeouts and quotas in the server and client's config files to quite large values, but still I am getting Bad Request error on the client.


Also the Bad request message is returned always in 1 minute 30 seconds after sending the request to server.


What the most unusual thing is when I use Fiddler or Charles to debug communication, everything works fine. Is it something like fiddler is pinging the IIS or service and hence its not getting timeouted or like that?




Following are the details:

Server Config:


 <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />

How to send binary data ( ogg audio file) using a web service?


Hi folks, I would appreciate any help or guidance on this topic:

How can I receive binary data (specifically an ogg audio file) using a WCF4 service?

The general idea is to define and host a WCF service inside IIS that returns an audio file (ogg file)

I have read some info related with using ByteStreamMessageEncodingBindingElement class to achieve this, also I read some topic related on using MTOM to attach a binary file. It seems that it can be several ways or approaches to achieve this.

So any guidance on the themes and/or examples for the better way to solve this point would be very appreciated.

Thanks in advance.



how to send the dump file to Microsoft, is this a pay service?


Since my SQL2000 server has the "insufficient memory error 701" when doing tlog backup, it happens randomly, I applied the hotfix, increased physical memory from 2GB to 8GB with awe enabled, max server memory 6GB, it still happens sometimes when backup less than 100MB log (active log should be less than it). I tried incrase memtoleave g512 and .... whatever suggested on the forums etc. the problem still not fixed permanently.

I was suggested to dump the sql and send microsoft, but how and is there a charge?

Uploading Large files via Web Service | HTTP Error 413 - Request Entity Too Large.


Hello all -

I am trying to implement a Web Service, which accepts a binary file as a byte array for one of its parameters.  It's workings are based on this article:

Anyhow, the size of the file can be significant as the types of files being uploaded through the service are MP4 Video files.  The service works on my WinXP SP2 localhost, but when I implement it onto a 2003 Server and try to consume the service, I get the following error back from the web service:
The request failed with HTTP status 413: Request Entity Too Large.

I do a little searching around and find a few articles indicating that I need to adjust my "MaxReadAheadLength" property in IIS.  A good example of one of those articles is here:

The suggestion from the article is to execute the following command on the web server:
cscript adsutil.vbs set w3svc/1/uploadreadaheadsize 204800 

FYI, the adsutil.vbs is in your IIS's AdminScripts directory.  I'm guessing that the /1/ part of the command is th

Fax Services: Send Any Printable File From Your Program in Windows 2000


All versions of Windows 2000 have fax services built in, so sending faxes manually is as easy as setting fax options from the control panel. Faxes can also be sent programmatically in Windows 2000 using either COM Automation or the standard C API. The example in this article uses COM Automation with Visual Basic and MFC to programmatically manage faxing. The objects used for fax transmission, such as the FaxServer and FaxDoc objects, as well as their properties and methods, are explained. Because faxing of files you can't print can be problematic, this process is explained. Finally, this article implements a fax routing extension-a plug-in that exports standard functions and implements routing methods for processing received faxes.

How to set and map a Method in the Service file with endpoint elements and binding elements

Hi all, I have created a service file like OSService.svc in that i have two methods like one is FileUpload and FileDownload for e.g :- [WebInvoke(UriTemplate = "/fileupload/{fileName}" , Method = "POST" )]         [OperationContract]         void FileUpload(string fileName, Stream fileContents); same as Filedownload also.
