The best way to write a survey application

Question

I am trying to create a basic application that will have two separate components:
1. Constantly poll the external process and save the results in DB. 2. Grab the results from the database and display them on the web page.

I want to do this in .Net, so usually I say to make the first component in a Windows service, and the second in ASP.net with relational dbms, like a sql server.

The problem is that I want to use web hosting to deploy it, and they are not inclined to allow Windows services (unless you pay a fortune). So is it possible to execute the polling component on a separate asp.net page or to create a spawning workflow on a single asp.net page that will do the polling for me?

Any opinions / input appreciated. Thank:)

Answer 1

Read this blogpost regarding simple background tasks in ASP.NET . Some suggestions, lessons, etc. In comments. I think I remember the podcast where the site scale made this code go to the Windows service. You may / may not have the same scaling needs.

Answer 2

You may have a static method that sets up the polling flow in ASP.NET, so yes.

ASP is mainly designed for requests, not long processes, you can get something working, but it will never be as reliable as something intended for work.
