Re: Where to call curl_global_cleanup in a UNIX shared library?

Thank you Daniel for your help.

Because I cannot control the behaviour of the scripting engine,
I decided to call curl_global_cleanup at the end of each request.
I do not call curl_global_init explicitly because
I've learned that curl_global_init is called automatically by
This way each request against my library triggers an global initialization
and cleanup. I've been testing my apps on Win32 and Linux and
this procedure seems to be working.

Any comments?

BTW, cURL is terrific.
