Creating a url_head routine

[daveslater1964]

In the web world there is now a HEAD verb that is similar to GET but returns meta data for an object, not the object.

Is there anyway to incorporate this into the library?

Kind Regards,

Dave

Have you tried HTTP_req() ? It is not method specific.

I have seen it and am looking for some examples on how I might use it.

HEAD has existed since at least HTTP 1.0, which was released in 1996.

HTTP_req, HTTP_string, HTTP_stmf are all intended to work with any HTTP method.

here's a simple example (no idea what you're planning to do with HEAD, so not sure how helpful it is)

Code: Select all

**free
ctl-opt dftactgrp(*no) bnddir('HTTPAPI');

 /copy HTTPAPI_H

dcl-s rc int(10);
dcl-s url varchar(1000) inz('https://www.scottklement.com');
dcl-s modified varchar(100);

rc = http_req( 'HEAD': url: *omit);
if rc <> 1;
  http_crash();
endif;

modified = http_header('Last-Modified');
snd-msg 'Page last modified:' + modified;

*inlr = *on;
