Problem with MSN search results

[BPJSURF]

Working with SEO optimization for a HVAC supply catalog http://southsidecontrol.com
They are doing well in the search engines but I have run into a problem with MSN result pages. We recently updated their parts catalog using a data import. We build the import in a proprietary unix machine and import to Actinic as a flat file of about 6000 items. When we import the data feed the product information is updated as desired.

However we have found that some product information change and this causes problem with MSN search results. Its almost like MSN has cashed pages of the site. You can view product and get search results from MSN searching when the product has been removed from the catalog. When you hit the Add to cart it gives you the proper Actinic script error with the explanation that the product has been removed from the catalog. Now Actinic is working correctly because there is no product. Does anyone have any expereince with MSN SEO? Have you seen these cashed pages before?

here is an example:
Go to http://MSN.com
search on the part number: TH8110U1003
Note that it is first and second in the search results :-) nice
the first result takes you to the home page and works great
the second result takes you to a product page which does not exist in the product catalog after the new product inport feed from the unix system.
The second result displays a page: http://southsidecontrol.com/acatalog...hermostat.html
IF you attempt to add to cart you get the script error.

Now go to http://southsidecontrol.com
Use the web site catalog search and locate : TH8110U1003
The search returns a vaild page and locating the product through section navigation allows a functional purchase. http://southsidecontrol.com/acatalog...stat_3015.html

So we know that the product and catalog work correctly. When searching in Yahoo! and Google there is no issue. I have not had problems with MSN search in the past however they have recently implemented their new search technology and it seems to me like it is cashing the page results. My immediate reaction is "Am I missing something simple here?"

IF you have any expereince with MSN or Search engines cashing pages I would be very greatful for your input.

thanks

Ok so I did some research and I am positing some links for those people who are SEO junkies like myself. The only real cure for the problem is to get the site reindexed by msnbot because msn search serves cashed pages. Beleive it or not I think this is a good thing!

here is a site from msn search that has the simple answers you need as a site owner or webmaster:http://beta.search.msn.com/docs/siteowner.aspx

Also take a look at this thread if your looking for some more information:

I will have to update the robot.txt file to instruct msnbot to re index our sites more often, this will atleast give Msn search users a better chance of getting a cashed page that is good.

I am considering modifying the script error message to better instruct users on the problem but I need to think of the consequeces of that change. I am interested in anyones opinion on this subject. If you have thoughts or expereince with the issue I would love to here from you.
