Need instant alert of web page change

by Technically Challenged / July 14, 2009 5:30 AM PDT

Is there any software out there that will monitor a web page and give me instant or near instant notice of any changes?? (such as the addition of 1 line of text). We have a client who posts new available assignments on their web site. Once logged in, I can view my account info and any new available assignments.
Any other approved vendor in the area can also view available assignments and depending on how busy things are, these assignments are sometimes available for less than 60 seconds. If they are not claimed in the first 2 minutes, they are emailed to the vendors in the area and rarely last longer than another minute or two. I have a Windows XP laptop with Avant browser constantly monitoring the site with browser set to refresh every 2 minutes. This works fine except that you need to glance at the laptop constantly and it is easy to miss. Is there any software that would give me an audible alert or some kind of alert to my main computer which is running the Windows Vista OS??

You can write it.

http://www.google.com/search?hl=en&q=wget finds wget.

So how hard would it to write a script that used wget and then another file compare and when there was a change to beep?

No I am not offering to write your script or even google if your software exists. But it looks like a 30 minute software task.

A librarian colleague of mine recently suggested the Copernic Tracker. Here is what she says:

To download or check out the tracker programme, go to http://www.copernic.com/en/products/tracker/
Copernic Tracker automatically looks for new content on Web pages, as often as you like. When a change is detected, our Web site tracking software can notify you by sending an email, including a copy of the Web page with the changes highlighted, or by displaying a desktop alert.
I just saw that the programme costs less than I told you yesterday; only 30 US dollars
A free trail is offered.

Universal monitoring of web content changes with Wachete
by Hrncek / October 16, 2015 3:39 PM PDT

I'm recomending Wachete. Suitable for monitoring part of web pages or whole web portals with subpages several levels deep.
Able to detect changes, show differences, even able to understand numbers and paint graphs.
Available on web, or as Chrome plugin or for all mobile platforms.
