CHANGED MODE 3? and EXIST? do not work by type of URL

Question

Does any REBOL 3 guru know why modified? functions modified? exists? and size? don't work on R3 when targeting url?

These functions work fine in local files.

I am very familiar with R2, but the behavior of R3 at times seems strange. I use the stock code compiled from the open source release on December 12, 2012, and run on Windows 7.

Answer 1

Basically, support for these functions has not yet been implemented for most URL schemes (see, for example, # 467 for HTTP or # 1826 for DNS).

All three functions mentioned use QUERY as the main action to obtain the necessary information. Therefore, it is a matter of implementing a specific URL scheme, also properly implementing full QUERY support.
