Hi guys,

I am brainstorming for the best way to make seo-friendly urls for a large amount of products (2000+) in a store running on the Sysdatanet Store module. Right now I am considering writing a scheduled task that would generate an entry in the SiteURLs.config file for each product in the Sysdatanet Store. So my question to you is, how might having a 2000 line SiteURLs.config file effect my installation of dotnetnuke? Would DNN have to parse this file and review every entry time a user makes a page request? Or does DNN have a more elegant method of handling this data?

TIY for your ideas everyone!

After looking at the code for UrlRewrite, it shouldn't be an issue as the file SiteUrls.config is loaded once and a dependency is created which means if the file changes it is reloaded.  From that point on it simply takes the incoming request and does RegEx a checks against the list of URLs.  That should be very fast given that it will already be memory resident.

Although the expressions are cached in memory, an O(n) operation on every page request could still be potentially prohibitively expensive -- especially with complex expressions.  4.9 contains a performance improvement for this matching, and in discussing this improvement, I did a little benchmarking (with a simple expression) that includes some data with n = 1000.  Read more here.
