How do I secure my ASP code on client servers?

Hi all,

Desperate for suggestions.

I have a windows app that uses a license key to allow the number of users the client has paid for. (say 13)

We've been asked for a web interface.

We want the client to be able to run the software on their servers.
But only with our license. And user count.

We have decided to start with supporting the clients with the least requirements.
as in HTML (can't do it)
then ASP (can't offer ASP code as client can remove licensing scripts etc.)
then ASP.NET 2which is supposed to do this with wizards etc....

So we have to start with ASP/IIS.

Could anyone make any general positive contructive suggestion as to how to secure a classic ASP web interface to a (say) MSAccess Database?

Please remember that I need to secure the database with a license against tampering by the client.

We're NOT asking exactly how to do it.
Just which direction and perhaps which components to consider.



We're 99% convinced we need to use .dlls to secure everything in an ASP/IIS environment.


Has anyone heard of any FREE (preferably)"embed ASP/IIS into .dll" products?

Has anyone heard of any NOT FREE"embed ASP/IIS into .dll" products?
Has anyone had any experience in doing this?
Is so, was it too hard? easy?

Could anyone please post any hyperlinks to this subject?

You can encapsulate your business logic in a VB DLL and your ASP code can access the public functions provided by the DLL. Problem is most hosts don't allow custom DLLs. Works great though. If the client is hosting in-house and ASP.NET is not available, this is a viable solution.

 

Excellent!

Thanks gents.

We can't limit our sales to .net only.

Anyone have a hyperlink on how to "encapsulate your (ASP) business logic in a VB DLL "?

I've only been able to find a single reference to enhance the 404 error report.

Again, just a hyperlink to get me started.

"...most hosts don't allow custom DLLs..."
Does anyone know if DiscoundASP.Net allows custom dlls?
I'd love to be able to tell my clients that they can get award winning support from DiscoundASP.Net.
Thanks again!

If you do a search, look for "ActiveX DLL in ASP".
