You can do this with a ns_register_url, like this:
ns_register_proc GET /* Redirect
proc Redirect { conn spec } {
set host [ns_set get [ ns_conn headers ] Host ]
set url [lindex [ns_conn request 1]]
if { $host != "$correcthost" } {
ns_returnredirect http://$correcthost/$url
}
}
I just whipped this up on the spot without proper testing, so try it
out and see, it should get you started.
Note that I only did this for GET. I don't know what would happen if you
redirected a POST, and besides, you have control over where a POST goes
anyway, usually (because you made the form)
Also, I made my own procedure, which I use, in place of ns_returnredirect,
which at least tries to always redirect the user to the sameg host he came
in on:
proc dummy_returnredirect { href } {
set return $href
if ![string equal -length 4 $href "http"] {
set host [ns_set get [ ns_conn headers ] Host ]
set return "[ string trim ${host}/$href ]"
regsub -all {//} $return {/} return
set return http://$return
}
ns_returnredirect "$return"
}
Note that:
* if you give an absolute URL, it does not attempt to mangle the host
* if you do: "dummy_returnredirect mypage"
it goes to /mypage, and is not relative to wherever you currently are
It's crude, but it works. The idea is, instead of having a somewhat
clumsy registered proc you have to go through for every hit to your site,
just make the redirect do the Right Thing in the first place.
