Thanks for the tip about ns_conn headers, which gets me over the
immediate problem.
My proc is now able to detect a host and ns_returnredirect successfully.
However if the test for that host fails the proc now returns nothing,
i.e. a page of 0 bytes. What I want it do is just return the page
requested, i.e. just treat the request in the normal way.
If I ns_returnredirect to the original location it gets into a loop
(four requests in access.log) and the browser says:
"Firefox has detected that the server is redirecting the request for
this address in a way that will never complete."
What is the correct way to handle this? Does the proc need to return
the entire original page? Would that be [ns_conn content] or is there
more to it than that? The result should be transparent, as though
there were no registered proc involved.
Again, I wonder whether my approach to the initial problem is right.
I'm using AOLserver 4.0.10

The HTTP Host information will be located in the request headers which
you can grab and put into an ns_set like this:
set headers [ns_conn headers]
You can then get the HTTP Host header with:
set host [ns_set get $headers Host]
What you're getting with [ns_conn host] is not the HTTP Host header
but rather the host portion of the URL that was requested, e.g. if the
client requested
http://scottg.net/index.adp
[ns_conn host] will return 'scottg.net'
/s.

I'm trying to set up an ns_register_proc to redirect requests to
what used to be a separate website that now points to mine to a
directory on my site. (The client does not want to use a virtual
server.)
My plan is to test the host of the connection and ns_returnredirect
if it matches the formerly-separate host.
The docs at:
http://panoptic.com/wiki/aolserver/Ns_register_proc
say
"The conn argument will be filled automatically with the connection
information."
so I expected it to be an ns_set or array, but it does not seem to be.
It contains "cns0" on the first use after a server restart, then
"cns1", "cns2" on following uses.
Can someone give me a hint how to use the conn argument in:
ns_register_proc GET /* misaEast AAA BBB
proc misaEast { conn {arg1 one} {arg2 two} } {
...
}
I've also tried using [ns_conn host] within the proc but it just
returns "". Other ns_conn options, including url and location,
return the expected values. Is there a way around this?
Should what I am trying to do be done a different way?
Thank you,
Eric Lee
