How to consume WCF (using webHttpbinding) JSON in a asp web

Hi any tips to consume WCF (using webHttpBinding) in JSON format in a ASP Web Application?

 

Almost all tutorials i found uses basicHttpBinding or wsHttpBinding. Im not sure how to create a asp web application to consume my WCF service.

 

My idea is:

 

a form with a text field and a submit button, so when i write and click submit, should call WCF service to query like http://localhost/Service1.svc/wsquery/$searchstring where $searchstring = text field value from web form. 

 

thank you.
