- On Apache/SSL servers syllabus should always be served by http:// to avoid
"mixed content" issue when syllabus is an external resource on http:// server).
- Set $env{'request.use_absolute'} and pass in args to start page so postdata
is preserved. (bug 6662).
- Code used for same purpose in rat/lonwrapper.pm rev. 1.44 for external
resources moved to lonacc.pm to facilitate re-use.
- Detect if syllabus template replaced with uploaded PDF or link to external
PDF file, and send as arg in call to lonwrapper.pm, to circumvent lack of
scrolling for multi-page PDFs in iframes on iOS.
