Correct, it sounds like you do need a modified httpd.  After recognizing
"/magic" and before doing the execl(), it would use the supplied Host:
header line to select a new namespace.

Not yet.
Maybe I should modify httpd for this purpose.

I tried to use plan9 for hosting service OS. I should treat hosting
service user as a computer beginner.
I afraid the following situation.
User A(his domain is domain1.org) creates cgi "somecgi" and user B(his
domain is domain2.org) create same name "somecgi" cgi but different
program.

Try pegasus, from http://plan9.aichi-u.ac.jp/pegasus/eman-1.2a/
I use it and runs fine.

Moroo,

Did you get a satisfactory solution to having /magic/somecgi
behavior depend on the domain name?

The solution is not to use /sys/lib/httpd.rewrite, because httpd applies
that only for normal file delivery.  Magic is considered as a mechanism
for the developer to have total control, so we jump to that with very
little processing.  However, your somecgi command linked against libhttpd
does have convenient access to hc->head.host extracted from the HTTP
headers, so you can readily personalize the behavior by domain name.

I'm wary of turning this over to shell scripts.  One needs to be
very careful about processing strings coming from the bad guys.  Doing
it in C where you know precisely what is interpreted seems safest.

Eric

Yes. but in this case I have to know cgi program name.

One solution is that I change httpd to Pegasus.
Or bind cgi directory (for example /usr/domain1/bin/ip) on /bin/ip/httpd
each access.

Sure. it works maybe. But I don't want to display domain1 two times.

You could write a script that mux's the requests and execs the correct
script

The domain requested from is in the headers.

I did a script you might find useful. In the archives it's at :

The URL I posted in there is not live atm.

I think the above example executes the same script
`/bin/ip/httpd/somecgi'.

As a workaround, how is to place script in
	/bin/ip/httpd/domain1/somecgi
and access it with
	http://www.domain1.org/magic/domain1/somecgi

I'm sorry I haven't tried.

[9fans] httpd and magic

[Moroo Jun]

On httpd with virtual host, I have a problem.

www.domain1.org and www.domain2.org hosting with virtual host on same
plan9 box.
cpu% cat namespace.httpd
bind /usr/domain1/doc /usr/web/virtual/domain1
bind /usr/domain2/doc /usr/web/virtual/domain2

cpu% cat httpd.rewrite
http://www. domain1.org    /virtual/domain1
http://www. domain2.org    /virtual/domain2

In this case, can I use *different* cgi program which having same name?

for example,
http://www. domain1.org/magic/somecgi
and
http://www. domain2.org/magic/somecgi
