Application Startup

[weeerob]

Is there anyway to stop the application starting during the
Application_Start event in the Global.asax.cs file? I want to check a
license key at this point and not let the application start if it's
invalid. I've tried throwing an exception but that doesn't seem to
have any affect.

Thanks,



Rob.

Hi,

Why not ersponse redirect it if the license key is incorrect?

That would only intercept the first user on the first visit.

You could go further with that and also incorporate logic into the
session_onstart that checks to see if an application variable was set and
redirect there also. However, if you are looking for a registration key or
something, does that mean that the files are hosted on the client's server?
If so, how are you blocking them from just editing the global.asa and
removing the check?

Have Session_OnStart check an Application flag, and take appropriate action

Hi Rob,

Application_Start might not be the best choice since it will only fire once
when the app starts. I don't think there's a way of making the app not
load - throwing an exception there will likely have some unexpected results.

A better approach might be to use Application_BeginRequest or hooking up
something inside of a custom page class (avoids somebody messing with
Global.asax), or hooking up a custom HttpModule dynamically at runtime (or
chaining Global.BeginRequest).

I figured if I couldn't stop the application in the application load
then I'd have to use Application_BeginRequest. Now can I throw a 500
error in this or can I only do redirects?

Thanks,


Rob.

Try my suggestion. I have it working here.

I see you've considered session solutions.

Perhaps in Application_Start you could actually change the IIS user context
to an invalid account? The application could not start the next time with
an invalid service account
