Why monitor web pages for changes?
It is no surprise that the rollover weekend is coming for Y2K.
What is surprising is how manufacturers are notifying their users of last minute
updates, patches and workarounds over the first weekend of the new century. Most are
posting any required support information to their own web pages and expecting you to be
aware of the new information there. This might be an acceptable solution if there
were only one manufacturer that supplied all of the software and only one page to
check. The problem is that most companies have several hundred suppliers of software
and there is no time to manually check each vendors web page continuously for the latest
Methods of monitoring web pages
There are several methods available to monitor for changes.
Here is a brief list:
- Download the directory containing the page. Monitor for
changes in date/time stamps at the directory level.
- Download the web page, calculate a checksum (or CRC).
Monitor for changes in the checksum.
- Download the web page and store the complete web page on the local
hard drive. Monitor for changes by comparing the local copy with newly downloaded
Our new tool WebCompare solves the problem by allowing you to
load a list of web pages into its Access database, specify the frequency to visit pages
(the minimum is every 2 hours or you can manually active the cycle as often as you like).
WebCompare will then compare all the pages in your list and notify you of any which
have changed. Once you have confirmed the change, it loads a fresh baseline of that
page and continues monitoring for the next change.

|The short answer is that it will not give you what you need.
The longer answer is that you have no control over when your page is scanned (it is
done at most once every 24 hours) and the email notification may be lost or delayed.
During the Y2K rollover those are unacceptable. You will probably want to
coordinate the scan to be completed shortly before systems are brought up and every few
hours thereafter. |
|Why not manually monitor web pages|
|Actually, manual monitoring is ideal, if it were not for the
fatigue and speed factors. Machines are much more likely to continue in their
deligence, if there are no problem reported in the first couple of hours after the
