[galaxy-dev] Apache proxy, SSL, and UCSC get data

I'm having trouble after setting up SSL on our Apache proxy for Galaxy. When I try to import data from UCSC, Galaxy tries to go to the http (non-ssl) url for UCSC and thus generates a security error in the browser and the request is blocked. I have added

RequestHeader set X-URL-SCHEME https

to the httpd.conf and that appears to be working. Is there something else I need to do? Should I patch the data_source tools to use https in the xml tool definitions? Thanks for any advice.
