问题
Came across to this defect with ASP.NET RC refresh while using VaryByParam="" instead of VaryByParam="None".
Caching WORKS, but page http://www.yoursite.com and http://www.yoursite.com/home/index will be cached separately it seems.
What is the difference between VaryByParam="" and VaryByParam="None"?
edit : I mean VaryByParam="" not VaryByParam="*" cause the bug still exists with VaryByParam="*"
回答1:
VaryByParam="*" will create a new cache for every different parameter passed.
VaryByParam="None" will create one and only one cache, regardless of parameters.
回答2:
Route elements are not considered parameters for OutputCache.
What is VaryByParam in asp.net?
