Well I had a look through the code. I'm no developer; I'm not able to 
understand much of the code, so I've just been simply grepping for 
http:// in a recent tarball from GitHub :-D

One thing that caught my eye was this result:
$root_url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') ? 
'https://' : 'http://';

 From this, I would deduce that MythWeb is trying to determine if the 
web server that it's running from is actually serving on HTTPS or just 
HTTP and adjusting $root_url accordingly. It may be that because Apache 
on the MythTV backend server is only running HTTP and not HTTPS, MythWeb 
is only outputting HTTP links and refs... Or am I on the wrong lines?

Yes, see my response to Ron below. In short; there are lots of requests 
for HTTP even though the page was re-written by mod_rewrite to HTTPS.

I'm pretty sure I saw this happen when watching the requests in Firebug 
as I browsed around the listings area of MythWeb - the request for the 
page is re-written successfully to HTTPS, however all links from the 
page show up as HTTP, for example if you hover over a programme title. 
If I attempt to change the time frame, I do indeed get lots of requests 
logged for HTTP, even though the page I was navigating from was served

Are you using mod_rewrite to force HTTPS, or is MythWeb actually running

As far as I know, yes. I don't have any issues with forms in any of the 
other sites I run through reverse_proxy.

Unfortunately not - I see the same behaviour, no matter what I use to 
change the time frame that I'm viewing on the listings page.

Thanks guys.
