Re: Generated pages date

Hi, You should tell the url-minder people that their page comparison is broken. There's just too many sites out there that have tiny little differences on each reload, and there are much better ways than doing a plain binary compare, or having everyone add custom tags to their HTML. One suggestion is using a partial checksum algorithm: you split the document into N parts and make a checksum on each part. If at least N-M checksums are the same, two documents are considered equal. Try starting off with N=9 and M=1. It can be tuned by adjusting N and M or splitting the document in different ways (per-byte, per-line or looking at HTML structure). - Stig [jhlavon@relaxtime.cz] > Hi, > oop, sorry, you don't understood me - problem isn't in words > "generated/changed" > but in date value after it.
