18 September 2002 MTCHFILE.REX: The "find best matching files" SREhttp/2 procedure. MTCHFILE.REX is an example of a "not-found file procedure" that can be specified using the NOT_FOUND_FILE parameter (in your possibly host-specific SREHTTP2.CFG file). Syntax (assuming MTCHFILE.REX is in the SREHTTP2\PROCS directory): not_found_file='!PROCS\MTCHFILE.REX' MTCHFILE.REX will find several names, in the "directory" of the requested (but not found) file, and create a linked list to them. However, it will NOT display links to directories and filenames (possibly wildcarded filenames) listed in the DIR_EXCLUSION parameter. Note that if a bad-directory is given, then a "best match" for the file in a higher level directory is attempted (which might be /, the possibly host-specific data directory). ------ Discussion of not-found-file procedures ------ The following arguments will be passed here (and to any other not-found-file procedure invoked through use of not_found_file=!procname) docfile -- the file the selector matched (which could not be found) who -- numeric client ip address selector-- the request selector verb -- the method (it will almost always be GET) user -- username (or '', if no username is available) verbose -- the verbose flag privset -- the client's privileges transaction -- the SRE2003 transaction # tempfile -- a filename that can be used as a temporary file host_nickname -- the host_nickname MTCHFILE.REX does not use most of these arguments, but other procedures might. MTCHFILE.REX (and any other of this not-found-file class of procedures) must return a string containing a fully specified HTML document (complete with ... . SREhttp/2 will then use the contents of this string as the response to the client.
