Multithreaded http downloads
Hi all,
I've got a service that users can use to download files from a http. I want
to add functionality so that a user can supply many urls and the service
starts to download the files. So I wondered if the way described here[1] is
the corrects approach, section about Multithreaded request execution
Cheers, håkon

Generally each execution thread should have a local HttpContext
instance. Sharing the same execution context between multiple threads
does not really make sense and may cause issues with some protocol
interceptors. Though, one may share some objections between multiple
contexts such as cookie store or auth credentials provider.
Hope this helps
Oleg

Am I correct that BasicHttpContext must not be shared between threads? Would it be ok to share SyncBasicHttpContext? Or does it never make sense to share the context?
