GIS/Mapping solutions that provide easy access to routing data

Question

I'm look for a GIS/Mapping tool that will give me easy SERVER-SIDE access to route information (specifically, trip time and distance) in an ASP.NET web application. From what I can tell, Google and Yahoo maps do everything client-side in javascript, but neither provide services to retrieve just the route information. I'm interested in both free and paid products. Also, if you have experience with a product I like to hear about what you think (complexity of API, runtime performance, likes, dislikes, etc.) JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

ESRI's ArcGIS Server and ArcWeb services provide point-to-point routing. You have full control over creating the data (if you want), changing the data, customizing parameters, and even adding dynamic cost analysis. Server might be a bit heavy-weight for JUST routing as its a full mapping and analysis server system. ArcWeb is an online service where you can buy just the services you want. Another option is Oracle Spatial. They have some built-in networking/routing capabilities to do point-to-point routing. I personally have been unable to get it to work, but I've heard second/third-hand comments that it works, but has the normal complexities of Oracle (i.e. not a DIY job). MapQuest also has a comprehensive set of API's (much better than Google or Yahoo IMHO) that can do routing without a map. Not sure what their licensing/costs are and how they compare to Google/Yahoo for non-personal use. (One note: many of the "free" services require you to pay a license fee for non-personal use... they might ignore you until your traffic gets high enough for them to notice so watch out)
