An awesome routing engine for ASP.NET MVC 3 and 4
The free edition of MVC Extensions v1 is a no-cost, full-featured version of the product, which comes with no redistribution
rights.
In contrast with the purchased, regular edition, the free edition appends the copyright text of the product to each (X)HTML page that passes through the SEO routing system.
Apart from that, the software does not have any other limitation and can be freely used both for personal and commercial use.
