Okay, figured this out.
in vcl_recv I check req.http.Host, and if it's wrong, I set it correctly
and throw 751, then in vcl_error:
if(obj.status == 751) {
# redirect
set obj.http.Location = "http://"; req.http.Host req.url;
set obj.status = 301;
This seems to work. Can anybody see any problems? Is it bad to set
req.http.Host? Will that string concatenation above always be well formed?
Thanks,
Chris

But the req.url doesn't seem to have the domain name in it, which is
what I want to redirect...

You need to tell the browser the new location in vcl_error. I have
something similar for mobile redirects.
First in vcl_recv catch the event:
if( ... some condition ... ) {
set req.url = regsub(req.url, "(.*)",
"/mobile\1");
error 750 "Moved Temporarily";
}
Then handle it in vcl_error:
if (obj.status == 750) {
set obj.http.Location = req.url;
set obj.status = 302;
return(deliver);
}
You can specify obj.status = 301 of course.

I'd like to do a 301 from a.com to b.com, but preserving the whole

The regsub isn't allowed there. Can I stuff it in a header that I
can get in vcl_error?
You probably can. What I do for redirects is to rewrite the req.url
and then use that in the error statement, i.e.
set req.url = regsub (req.url, "rewritefrom", "rewriteto");
error 751 req.url;
For your particular case where you don't actually want to rewrite
the URL but instead only change the host part of it, I would do
something like:
if (req.url ~ "(?i)^/vanitypath")
{
set req.url = "http://b.com"; req.url;
error 751 req.url;
}
Note that the host isn't present in req.url (use req.http.Host for
that) - so in the first example, "rewriteto" should start with a
full protocol specification (http://...";).
Most browsers work fine if they're told to redirect to /foo, but I
don't really like relying on it.
