[squid-users] Accelerator http to https

[creditu at eml.cc]

I'm in the process of converting all our sites from purely http to https
using squid accelerators .  During the initial roll out both http and
https will be accepted.  After that we want to only accept https, so a
redirect from http to https will be needed.  What I have below seems to
work, but I would like to keep the original request (URL and PATH) in
tack instead of redirecting them to the main page.  I know in 3.2 and
higher you can use FORMAT TAGS (%H%R), but I'm stuck using 3.1 for the
near future. 

 Any possible work around that I might be able to use.  The only thing I
 can think of is to send it to an ERROR page with some code to do the
 task.  Does squid support any coding options in custom error pages.
