The server committed a protocol violation

Question

User1887777618 posted

I created a asp.net 3.5 web service using the visual studio service template. After that without modifying it i published it to the server.

Now when i am trying to add the service reference it shows the below error.

There was an error downloading 'http://test1.owdaro.com/service1.asmx/_vti_bin/ListData.svc/$metadata'.
The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF
Metadata contains a reference that cannot be resolved: 'http://test1.owdaro.com/service1.asmx'.
The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF
The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF
If the service is defined in the current solution, try building the solution and adding the service reference again.

what settings or configurations do i need to fix it. Or can anyone tell me of a walthrough or steps to manually add the web reference.

Lots of Thanks

finally solved this. The protocol violation error was occuring because the Response Header was not in accordance with HTTP 1.1 specification and one of its entry contained a space. So next time i put anything in response header, there wont be a space in it.
