We have to move a site from apache environment to a new location that
runs Netscape Enterprise 2.01. The setup they have is all cgi-bin's in
/cgi-bin dir and also they don't know much what NscpEnt can/can't do. To
match their requirements I'd like to make sure if Ent 2.01 can do an
equivalent of Apache's mod_rewrite's:

RewriteRule ^/path/to/file$ /cgi-bin/foo.cgi

which means the browser still thinks it's getting content from
/path/to/file while it's actually getting a result from a cgi..Otherwise
i'll be having problems with relative links we're using..

Another thing is also if it (Ent 2.01) can run cgi's outside the
/cgi-bin dir (the guys there said it can't) and how to set up this..[*1]
If you can, can you run a cgi named foo.html as a cgi or is the
.extension the main match to determine what to do? [*2]

(In other words, can it do:
[*1]
ScriptAlias /some/where/else/ /httpd/htdocs/some/where/else/

[*2]
<Location /path/to/foo.html>
  SetHandler cgi-script
</Location>
)

Thanx for any help and if you could give me brief directives on
configuring that as I can't rely on the owners of this servers to know
how this is done..

Hopefully 2.01c or 2.01d, as 2.01 is not y2k compliant (and has been
end-of-life'd).

Yes. You may need to write an NSAPI to do this; essentially the NSAPI
changes a request parameter so that the server then acts like the client
requested a different URL (though the way we did it, the log shows the
original URI, _not_ the actual CGI path). The server then executes the CGI.
Next week I'll have to check which parameter that is...

There's no built-in way to do that, but you might be able to either write a
custom NSAPI function or use something like

<Object ppath="/full/fs/path/to/foo.html">
Service type="*" fn="send-cgi"
</Object>

...maybe!

1) Make a NSAPI function that does something like this, which I tested on
FastTrack 2.01:

/* Netscape NSAPI header files */
#include "netsite.h"
#include "base/session.h"
#include "base/pblock.h"
#include "frame/req.h"
#include "frame/http.h"
/* our PW-internal-redirect function */
int PW_internal_redirect(pblock *pb, Session *sn, Request *rq) {
        char *cgiPath;
        char *apparentPath;
        /* check parameters and ppath value (you could obviously change
            from strcmp() to a regexp compile/comparison if needed) */
        if (  ((cgiPath=pblock_findval("cgiPath",pb)) == NULL)
                || ((apparentPath=pblock_findval("apparentPath",pb)) == NULL)
                || (strcmp(apparentPath, pblock_findval("ppath", rq->vars)) !=
0) )
                        return REQ_NOACTION;
        /* looks like a match, clear the current ppath */
        if ( param_free(pblock_remove("ppath", rq->vars)) ) {
                /* make the rest of the httpd stuff think they requested
something else */
                pblock_nvinsert("ppath", cgiPath, rq->vars);
        }
        /* and we return from the function */
        return REQ_NOACTION;

2) Init your function in obj.conf and call it as a NameTrans function

# at the top
Init fn=load-modules shlib=/path/to/libMyRedirect.so
funcs="PW-internal-redirect"

# in an Object
# note both Path's are actually URI's, not Unix fs paths
NameTrans fn="PW-internal-redirect" apparentPath="/old/uri"
cgiPath="/cgi-bin/foo.cgi"

3) If you call this outside the "default" Object in obj.conf, you *might* need
to add something like the following three lines to that Object to make sure
the httpd runs the CGI as expected.

NameTrans fn="pfx2dir" from="/cgi-bin" dir="/full/unix/path/to/cgi-bin"
ObjectType fn="force-type" type="magnus-internal/cgi"
Service fn="send-cgi"

That's it.
