Tricky redirect/rewrite

I searched for this one, but found nothing ...

My old site is: cs.abc.edu/~cs4096
My files were at: cs4096@cs.abc.edu/public_html
My personal site: myname.com
My Github Pages site: myname.github.io

cs.abc.edu/~cs4096

cs4096@cs.abc.edu/public_html

myname.com

myname.github.io

When a user requests cs.abc.edu/~cs4096 they are served cs.abc.edu/~cs4096/index.html and so on.

cs.abc.edu/~cs4096

cs.abc.edu/~cs4096/index.html

Via the ISP hosting myname.com, I setup a CNAME pointing teaching.myname.com to myname.github.io .

myname.com

teaching.myname.com

myname.github.io

I want references to the old site, including pages below the top index.html, to be sent to teaching.myname.com where through the magic of DNS CNAME the URL goes to the myname.github.io site. In other words, users still go to the cs.abc.edu/~cs4096 but they are served from github.io.

index.html

teaching.myname.com

myname.github.io

cs.abc.edu/~cs4096

github.io

The teaching.myname.com -> myname.github.io bit is working fine. It’s the initial redirect/rewrite that is failing. The problem is that the ~cs4096 is included in the URL when it is passed to myname.com .

teaching.myname.com

myname.github.io

~cs4096

myname.com

That is, this

http://cs.abc.edu/~cs4096


ends up as

http://teaching.myname.com/index.html~cs4096


instead of

http://teaching.myname.com/index.html


and this

http://cs.abc.edu/~cs4096/Schedule


ends up as

http://teaching.myname.com/index.html~cs4096/Schedule


instead of

http://teaching.myname.com/Schedule


And, if you wonder WHY I’m doing two “redirects” here, it is because want the automatic rebuild of github pages that I can’t get at abc.edu or myname.com .

Thank you all
