It doesn't really matter if it's a name-based virtualhost or not. The same logic applies whether there's one VirtualHost or a hundred, and whether they're name-based or IP-based. > > On the other hand, if the above configuration disincludes the > > ProxyPreserveHost On setting, any fully-qualified generated URL will > be > > wrong. > > > > This doesn't just include URLs generated by Pyramid APIs like > route_url, > > static_url, and resource_url.

I'd rather apply this: "don't generate fully-qualified URLs in > your web apps, or you may have trouble running them behind proxies". You're eventually going to run into situations with middleware that unconditionally generates fully qualified URLs where I believe you're going to need to modify that to "always set ProxyPreserveHost On". But until then, you can try to ignore it by generating only paths, although I don't think that makes much sense given that it's so easy to turn on. > > If, as you've suggested, your solution will be to develop an > application > > with host-and-port-free URLs rather than to proxy the Host header, > is it > > really worth talking about? > > > I was just trying to fully understand why you think ProxyPreserveHost > always made sense.

Sure, apologies if I sound dismissive, I just hate having long discussions about defaults. - C -- You received this message because you are subscribed to the Google Groups "pylons-devel" group.
