asp.net - PostbackUrl vs NavigateUrl

Question

Can someone tell me the different between LinkButton.PostBackUrl and HyperLink.NavigateUrl? I've got a asp.net 2.0 application that uses both methods throughout the application and everything works fine. However if I connect to the application over the company vpn all of the links that use LinkButton.PostBackUrl give me a (54) Connection reset by peer error and the HyperLink.NavigateUrl work just fine. I want to know the underlying difference between the commands so I can try to figure out what the vpn software is blocking that is causing the Connection reset by peer error.

Answer 1

NavigateURL: Submits a 'Get' request to the URL (just like if you had typed it in your browser)

PostBackURL: Submits a 'Post' request containing the information from the form to the specified URL; I don't believe this is commonly used
