comet

i need to update client on any changes occurred on server. for that i found 2 approach. 1. using ajax which is also known as reverse ajax for this purpose. 2. using COMET.

but i don't know exact difference in both.

my site contains news content and i want that news to be automatically updates when new news is entered by my CMS application. i have got hundreds of concurrent users on my web application.

please suggest me which approach should i use to get best solution. also please provide me good example's like for that so that i can implement it.

NOTE: i am using .net framework 2.0 but if its not possible in 2.0 then can also move to 3.5

Thanks.

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
