Which SSL protocols to allow for client HTTPS/SSL connections when crawling and searching, ie. for connections from Webinator to remote https:// URLs. The default is to leave all protocols enabled for maximum compatibility; the most-secure protocol will then be negotiated. However, sometimes the connection fails at (or soon after) the negotiation, possibly with the error message ``Missing HTTP response line in reply from ...''. This may be due to settings on the remote server that disallow certain SSL protocols. In such cases, disabling various SSL protocols under SSL Client Protocols may enable the connection to succeed.
