Hi John,
I see why you are doing that but I don't agree it is a good way to go, at
least for me. It looks like you are a corporate developer who builds for an
intranet that would benefit from the context paths. But, for me (internet
development - each site unique), it works out better for the whole team when
the dev (and qa) server is setup with virtual hosts (? I am not a sys admin,
so...):
Dev server
dev-site1.workingdomain.com
dev-site2.workingdomain.com
QA server
qa-site1.workingdomain.com
qa-site2.workingdomain.com
Live server(s)
www.site1.com
www.site2.com
This way everyone is working (and qa'ing) out of the same environment as it
will be when live.
As for my personal development, I do work on local machines at home (not the
dev box) whenever possible. We keep everything in sync with CVS. I also
have the 5 static IPs and keep a machine/static IP for each project. It is
easier for me (and everyone else on the team) to work without the context
path. I do see the context path as a problem in these containers especially
when working on large projects/groups with a variety of skills and needs. I
feel it is better to keep the same environment through the site promotion
process.
of course there are other ways to do it... Thanks for the discussion, Rob
