I'm running an async thread with the use of Task.Factory.StartNew(() to generate sitemaps. My problem is that when I call my method: 

Task.Factory.StartNew(() => generator.CreateSiteMapForSite

it builds the sitemaps every time.

In my method I check that it only needs to regenerate the files if it is older than one hour. Even though it still regenerate the files per each request, is there a way to handle this in a async thread ?

  • If you want help on code level, you should really post more code, for now I don't really get what you actually need to do. – Nick N. May 17 '13 at 06:47

Since C# 5.0 you can use the async and the await keywords, have a look at this MSDN page for more information:

You can wrap around the task in an if and generate a new one if the sitemap doesn't exist or if exists read the file's modified datetime see if it's older than 1 hour.

The better solution is to setup a scheduled task to run every hour and rebuild the sitemap.
