Asp.net web api not setting content length header

Question

I am building a RESTful services using web api. My client is a HTML5/Jquery application. The service and application works perfectly on IIS 5.1. But when i switch to IIS 7.5, i see the response contains a Transfer-Encoding: chunked header and my client doesn't understand/render UI elements(btw this HTML 5/JQuery stuff is done by a third party and i don't want to change their code. why should i ? after all, it was working fine till we moved to IIS 7.5). My questions are :

1. How/Where do i add a "Conetent-Length" http header in web api so that IIS doesn't "chunk" encode the response?
2. Is there a way to disable this encoding at the site/server level in IIS 7.5 ?

When i access the service from browser/fiddler i get the proper response(xml/json). I am using Json.net formatter.

Answer 1

Use

myHttpResponseMessage.Headers.TransferEncodingChunked = false;

to turn off chunked encoding.
