That can be done in quite a simple way.. the easiest way is to modify the
HTTP server so that it creates a temporary file, then calls up a routine
which handles the request and writes to that file, then sends and afterwards
deletes it.
Here's an excerpt from our Server:
..
tmpfile = (char *)tmpnam(NULL);
sprintf(buf,
"sh /LocalLibrary/httpd_index %s '%s' %s >/dev/null 2>/dev/null",
file,keybuf,tmpfile);
system(buf);
if(stat(tmpfile,&finfo) == 0)
{
sprintf(logbuf,"INDEXFILE = %s\n",tmpfile);
printl;
send_file(tmpfile,fd);
unlink(tmpfile);
}
..
This is a bit of a dirty hack, but it works just fine :-)
Hope that helps,
Chris
