Feature request: monitoring other type of resource than web pages

[mountains]

Firstly I’d like to thank you Baruch and all people from community for 
developing Web Secretary. That’s very good and useful software.

My feature request is that Web Secretary can monitor other type of resource 
than simply web pages like other text or binary files. For example, when I put 
into URL parameter some binary file, mayby PDF of archive file, Web Secretary 
simply download this file and treat it like text file showing differences in 
text mode, but result of this action is senseless. It will be great if Web 
Secretary just inform me that this file was change, and I on my own will check 
for differeces

Mayby this could be done if Web Secretary automatically recognize type of 
resource. So if resoruce is web page in (X)HTML, then Web Secretary work so 
far. If resource isn’t web page, but it is text file, Web Secretary compare 
text file without skiping (X)HTML tags. And if resoruce is binary file, Web 
Secretary simply check for timestamp and/or size of this file. If Web Secretary 
can’t automatically recognize type of resource the additional parameter will be 
solution.

It should be emphasized, that this is my reflections on how Web Secretary could 
realize this feature and maybe exist better technical solution, but I think in 
and of itself this feature is useful, becouse we have many type of file that 
contain information, but not everything is store in web page format.

I'm not Perl programmer and IT specialist, so in concern for the quality of 
code I can't provide patch.

Thanks and regards.
