Hi Mike & Claude,

first off it is quite possible that the options selected for building OpenSSL by the Fedora packagers are different from other systems and this might explain the different behaviour also the CQ certificates installed on Claude's system are not the same as Mike's. Another option is that Claude is in DL and the URLs being used there will be different because of the use of local mirror severs.

Here is a proposed solution given Mike's findings that we appear to be able to force the use of http URL schemes.

1) Use the static member function QSslSocket::supportsSsl() to determine if the system supports SSL/TLS connections, if not then use Mike's change to adjust redirect URLs (and the original) to always use the http scheme,

2) Add a check box to the sample downloader details panel to the right of the download URL line edit called "Disallow SSL/TLS" which users like Claude who are having local difficulties with SSL/TLS connections can check to force the use of http URLs only.

This proposed change should allow the SourceForge redirects to be followed as they intended except on systems where the OpenSSL libraries are not installed or not available or not working for us. This should mean that users on Windows who have not installed OpenSSL and fellow operators in regions where SSL/TLS is restricted like CO and EP land will all be able to get the sample files without issue.

I don't have time to implement this before the weekend but perhaps Mike can extend his patch to do this before then.
