I wanted to have a a default filename extension feature in aolserver,
where http://localhost/foo fetches foo.adp, so that URLs in a web
site don't need to show the .adp on every url.
I read in the archives that openacs has this feature via a filter
written in tcl, but I wanted the implementation to be fast, minimal
and relatively transparent, so I wrote my own patch.
What my code does is change a page fetch internally from:
http://localhost/foo
to
http://localhost/foo.adp
This .adp appending only occurs on URLs that have don't have an
existing filename extension on them. Note that this patch also works
correctly with directories that have a period in them.
I'm pretty sure my code below is harmless and appears bug-free, but
it's not generic enough as it currently stands to warrant putting
into the core. I could make it work of an
ns_param default_ext ".adp"
if the patch seems interesting to others and there were interest to
put it into the core. Given that it's a very small amount of C code,
the overhead should be minimal with this feature enabled.
To put this patch in, you should insert the code below in nsd/
request.c right above "request->url = ns_strdup(ds2.string);" Once
you're happy with the patch you can remove the Ns_Log line.

/* john buckman added 4/14/06 */
/* check if should add default filename extension of .adp */
/* only if no / on end of url which indicates a directory */
char * dotpos;
if (ds2.string[ds2.length - 1] != '/') {
/* if not . in the entire url, or if there is a dot before the
final / (indicating a . in a
directory name, which is ok, then add the default filename
extension */
dotpos = strrchr(ds2.string, '.');
if ((dotpos == NULL) || (strchr(dotpos, '/') != NULL)) {
Ns_DStringAppend(&ds2, ".adp");
Ns_Log(Notice, "added default extension to get '%s'",
ds2.string);
}
}
/* end john buckman added */
request->url = ns_strdup(ds2.string);
