Thanks, Dragan.
That's a novel solution. I hadn't thought of changing an environment
variable, but it sounds like it would work. As for a
web.config.base_url, in theory the web.homepath is supposed to do
exactly that. As far as I can tell, it's just broken (or at least
doesn't work how I expected).
For now, I'm using the function below. Instead of calling
web.seeother(url), I call web.seeother(make_url(url)).
If this is an acknowledged issue and a patch would be welcome, I could
probably take another shot at a more general fix that would hopefully
not have any unintended consequences.
I had also been grappling with how to handle links embedded in the
templates, but I just thought of a solution: Put a <BASE href="http://
example.com/myapp/"> tag with the application's base URL in the <HEAD>
of the base template.
