Gets or sets a value that indicates whether to invoke the method by using HTTP GET.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
The use of HTTP GET for invoking the Web service method follows the same guidelines for any other Web interaction. HTTP GET should be used only for operations where no sensitive data is exposed and when the server action does not have side effects.
Setting theproperty to true might pose a security risk for your application if you are working with sensitive data or transactions. In GET requests, the message is encoded by the browser into the URL and is therefore an easier target for tampering.
