Full page load. I'm not doing a single-page-app or anything like that.
I was able to add this to layout.html (after line 33 in my 2.14.6 copy) and
get expected results:
{{ if "lsrefresh" in globals():}}
<meta http-equiv="refresh" content={{=lsrefresh}} />
{{else:}}<!-- NO REFRESH -->
{{pass}}
I tried using CAT to wrap the strings, but that made a lot of headers
disappear, probably because of escaping issues. Now I just have to get my
controller function to calculate lsrefresh intelligently.
Thanks for the patient help.
