Are Application collection and Page.Cache thread safe?

[Max2006]

Hi,

Since Application collection and Page.Cache can be shared among all
sessions, I wonder if they are thread safe?

Thank you,
Max

Max,

Thread safety is disclosed in the MSDN help topic for a given class.

the collections are thread safe, but the objects you add to the
collection may or may not be.

Cache is thread safe.
Application is also thread safe as long as you remember to use its Lock and
Unlock methods.

Hi Max,

Application State is provided in ASP.NET for compatible with classic ASP
application and you need to perform lock/unlock over it to make sure
thread-safe. Application Cache in ASP.NET is built-in thread safe, that
means you can freely store and access objects in Cache entry without
additional lock/unlock(or other synchronize operations). However, I agree
with Bruce that you need to take care of the objects you want to store in
Cache, whether the objects (you'll store in Cache, or to share them) is
thread-safe is important if you'll take care of the concurrent accessing in
your web application.

BTW, I also saw your another thread "Can we use static table adapters in
highly concurrent web sites?" in the newsgroup, and some other members have
also replied you there. Please feel free to have a look also.
