How to detect page post back in HttpModule?

[Hardy Wang]

Hi,
I have a HttpModule in my ASP.NET application, in AuthorizeReques t event, I
want to detect if page is posted back. Is there a way?
using System;
using System.Web;

namespace MyModule {
/// <summary>
/// Summary description for PermissionCheck er.
/// </summary>
public class PermissionCheck er : IHttpModule {
// The stored application
private HttpApplication myApp;

public PermissionCheck er() {
}

public void Init(HttpApplic ation app) {
// Store off the application object
myApp = app;
// Wire up our event handlers
myApp.Authorize Request += new EventHandler(my App_AuthorizeRe quest);
}

public void Dispose() {
}

private void myApp_Authorize Request(object sender, EventArgs e) {
// I NEED TO DETECT POST BACK, IF SO I DON'T WANT TO RUN AGAIN

int userID;
if (myApp.Context. User.Identity.N ame.Length > 0) {
userID = Convert.ToInt32 (myApp.Context. User.Identity.N ame);
} else {
userID = 0;
}
string url = myApp.Request.U rl.AbsolutePath ;
}
}
}

Perhaps by testing the REQUEST_METHOD server variable ? A postback is likely
always a POST while you'll have a GET in other cases ?

That said I'm not sure it's the right approach (POSTs would be always
considered as authenticated ?)

You could also check if the referrer is the same as the requested page
by using the HTTP_REFERER server variable, that in combination with the
REQUEST_METHOD being a POST should confirm that the page is a postback.
