How do I view the size of the data posted to a form in the Chrome Developer Tools?

I am going through an old ASP.NET a开发者_开发技巧pp and turning off ViewState for Gridviews where it's not needed. This is reducing the amount of information sent to the server on postback, but I am curious how much.

In FireBug, I can go to the Net tab, apply the HTML filter, and expand the particular aspx file that got posted. Beneath that, I can click the "Post" tab, and one of the values it shows is the Content-Length of the post. (I had some pages uploading 4 megs on postback... YIKES!).

Does anyone know how to see this value in the Chrome developer tools?

As of Chrome 10, they've added the feature! It's Content-Length under the Request Headers section in the Headers tab. This tab is available when you select Network from the toolbar and then click on a file.

I'm going to pretend they did this because I filed the feature request. I changed the world!
