Tool for Visually comparing two websites?

I have recently had to release a new version of a website, after increasing the efficiency of some of its servlet interactions. However, now I need to be certain that the whole of the website still works as it should. What I need is some sort of tool to be able to compare the 2 versions alongside eachother, with this tool checking each pair of pages as I load them for visual identical properties. Definetely NOT identical HTML file properties, as this would be of no use to me at all.

I am in a rush to get an abswer, so any feedback would be greatly appreciated.


PS: Of course, the optimal tool would be which (given the 2 websites) actually deep-searches through them comparing each page visually to the other web site.

Such tool could have been implemented to use machine logic to do auto optimization in the first place. Please provide more technical details about the comparison requirements.
as far as i know there isn't a tool to visualy check the pages.
What you can do is a filecompare and check the pages that are different

You can try to get a free shell on *NIX, unless you have a *NIX machine for use. When you're there, upload the HTML pages there with FTP if you have FTP, then type:

diff -u file.html file2.html > compare.diff

Then, view compare.diff.


-     - Remove the line
+    - Adds the line

Hope this helps,
