Cache for asp.net user control


B

Billy Zhang

Here is a user control on the page, how do I cache it by user?
Currently I think we could put a server control for example ID:textusername
in the asp.net page whose value is username, so we can utilize Output cache
with varybycontrol to control the cache.

Queation:
If this is right direction, does this control ID:textusername need to be in
the user control or just in the asp.net page?

How do I check if it has been cached successfully?

If there are 2000 users, how do I check the memory the cache used?

Thanks,
-Billy

Hello Billy,

emm, not quite understand what do u want to get.
Cache the user name or the value of the control?!
To have the user-specific cache your can use the Session, or put the value
to the Cache class with the user name key and hashed by username (to make
it a bit secure in case of accessing this value from other user)

I want to cache a usercontrol by using Output cache.
There are two ways: VaryByControl and VaryByCustom.

Since I want to cache this usercontrol by different user, could i use
VaryByControl to control this?

If there are 2000 users, how do I check the memory the cache used?

Hello

To cache a user control / a page by user name, as you said, we can either
use VaryByControl (a trick) or VaryByCustom, but I believe VaryByCusom is a
more direct way to accomplish the task. There is a blog article may exactly
meets the need:
http://aspadvice.com/blogs/ssmith/archive/2007/10/29/VaryByCustom-Caching-By-User.aspx
Please try it in your user control, and for any other questions, let me
know!

In order to monitor the cache usage in asp.net, Steve Smith has written a
cool application that helps you monitor and manage your cache values in
ASP.NET. Read all about it here:
http://aspadvice.com/blogs/ssmith/archive/2005/12/03/Cache_Manager_Almost_Ready.aspx
There are other open source projects for the same purpose:
