info(“httpheaders”)

The info(“httpheaders”) function returns a dictionary with information about a just completed HTTP download.


Description

This function returns a dictionary with information about a just completed HTTP download. To do this, the first statement in the urltask( completion code should be the urltaskstatus function. Then at a later point, the code can use the info(“httpheaders”) function to get a dictionary that contains all of the available information about the download. The exact dictionary entries will vary depending on the server queried, but here is a typical example.

    Server=Apache/2.2.15 (Unix) mod_ssl/2.2.15 OpenSSL/0.9.8l PHP/5.3.3
    Connection=Keep-Alive
    Etag="4e6c5-b60f-4e4f0aea25200"
    Keep-Alive=timeout=15, max=499
    Content-Type=text/html
    X-Frame-Options=SameOrigin
    Expires=Thu, 09 Oct 2014 08:53:21 GMT
    Cache-Control=max-age=60

    Date=Thu, 09 Oct 2014 08:52:21 GMT

If you only need the header information and not the data itself, set the METHOD to HEAD. For example you might want to do this to verify that a resource exists without taking the time to download the whole thing.
