Re: web page update notifier

You could use a md5 hash to check if the file has
modified or not. It is much more accurate and safe than
only using a diff. In addition, using the MD5 hash will
make the storage for the file much smaller..

*someone said to use "HEAD", to check the last modified
date. This value is not safe/trustworthy.

It is much more accurate and safe than only using a diff. Accuracy is irrelevant for text documents. Either a line is the same, or it is not. Besides that, I'm especially interested in which lines are different, and how they changed. `diff` tells me exactly that. the last modified date. This value is not safe/trustworthy. It has proven to be worthy of my trust. Juerd # { site => 'juerd.nl', plp_site => 'plp.juerd.nl', do_not_use => 'spamtrap' }	[reply]
