Execute ASP code from ASP.NET: my weird idea results
Last week I wrote about my simple weird idea on executing ASP in an environment built with a VB COM object that execute a asp file through an Asp.net HttpHandler.
I added the necessary basic features to execute the old-classic DNA sample application: FMStocks 2000 SP2.
The asp extension is mapped on then aspnet_isapi.dll, a simple entry on my web.config, a simple HttpHandler receives all requests for asp files, passing Form, QueryString, ServerVariables, Session and Cookies collections and, after the execution of ASP code, reading some of them modified by ASP execution.
Most of the problems I have encountered were in parsing ASP code adapting it to the new execution environment: some words such as Clear, End and Write are reserved words in VB6.
I found that executing ASP code through my code is only about 5-10% slower than in normal ASP mode, but the "Average time to last byte" was about 200% slower, due the simulated environment.
I have demonstrated myself that executing and sharing state (Session and Cookies) between ASP and ASP.NET is possible, however my solution is not ready for a production site. I did not developed all possible ASP objects nor tested the solution with a lot of ASP applications.
But I am satisfied of the work done.
Depending of the feedback I would like share the code..
