I try to let the coreclient 6.2.25 work with it, but SSL communication for Worldcommunitygrid fails on different linux machines.

Other recent versions of libcurl with openssl0.9.8g/h/i/j are OK.

You may test if these bugfix works:


http://curl.haxx.se/auto/cvshistory.html

- Rainer Canavan filed bug #2255627 (http://curl.haxx.se/bug/view.cgi?id=2255627) which pointed out that a program using libcurl's multi interface to download a HTTPS page with a libcurl built powered by OpenSSL, would easily get silly and instead hand over SSL details as data instead of the actual HTTP headers and body. This happened because libcurl would consider the connection handshake done too early.http://curl.haxx.se/bug/view.cgi?id=2255627

It is now in the latest nightly tarball.
