HINTERNET safe for multithreading ?

[hspc]

Hi
are HINTERNET handles safe for multithreading ?
can i pass handles returned from InternetConnect or InternetOpen to many threads ? (in the CreateThread API)
what about windows handles in general ?
thank you in advance :)

Well...a handle itself cannot be multithreaded on its own since it is basically a simple datatype. However, I think you want to know whether you can use the same connection within different threads.

May I first ask what you are trying to accomplish? In other words, why would you like to pass this connection to several threads?

Hi
thank you for replying

yes this is what i want to do.

I read in a MSDN article that it's better to create 1 session using inInternetOpen and reuse it. And I thought it's the same for InternetConnect since i'll access the same server.

But i also read in another MSDN article that each thread should create it's own CInternetSession and CInternetConnection (I'm not using MFC but the concept is the same)

I prefer to have each thread create it's own session and connection if this won't affect peformance.

any suggestions ?:rolleyes:

Well...I would also rather use a separate connection instead of sharing one throughout the system. I haven't dealt with this 'CInternetSession' that much, however, I would not see any reason why having multiple should decrease the performance of your application. I would rather see a decreasage due to a limited server... :cool:

seems that i'll share the session. and use multiple connections !!
more suggestions ?
