This could be a side effect of this URL. I change to my work's URL being "https://www.nikhef.nl/"; and it worked on my laptop. So your code should've worked too, but my libcurl is 7.28-1 and using DarwinSSL at the moment. I moved it to my CentOS 5 VM and observe the exact same problem. I'm using the same stock libcurl version there and indeed something is not right. My second call to my URL failed. I believe the OpenSSL context is not reset properly or something along those lines in the version curl-7.15.5-15.el5. My intermediate conclusion is that this problem is solved in a future version of libcurl. Oscar
