The earlier implementation of the modification that results in moving home.asp to the root of your web site had a limitation in that it did not support the AJAX product preview.  This limitation no longer exists.

The entire process is documented here:
http://wiki.earlyimpact.com/how_to/move_home_page_retain_ajax - http://wiki.earlyimpact.com/how_to/move_home_page_retain_aja x

The short version of what changed is as follows:

·         If it does not already exist, create a folder in the root called images.

·         Copy from the “/productcart/pc/”images folder all of the .png files related to the AJAX popup and place them in the images folder in the root of your web site:

o   topcap.png

o   titlemiddle.png

o   contentmiddle.png

o   bottomcap.png

o   pngfix.png

o   up-right-combo.png

o   up-left-combo.png

o   lower-right-combo.png

o   lower-left-combo.png

·         Copy the following files from the “/productcart/pc” folder to the root of your web site:

o   inc_PrdCatTip.asp

o   xml_getPrdInfo.asp

·         Edit inc_PrdCatTip.asp

o   change the tag that points to ei-tooltip.css so that it points to “productcart/store/pc/ei-tooltip.css”

o   change the tag that points to ei-tooltip.js so that it points to “productcart/store/pc/ ei-tooltip.js”

o   change the tag that points to XHConn.js so that it points to “productcart/store/pc/XHConn.js”

o   locate
myConn.connect("xml_srcListPrds.asp", "POST", GetAllValues(document.ajaxSearch), fnWhenDone);
Change the statement as follows:
myConn.connect("productcart/pc/xml_srcListPrds.asp", "POST", GetAllValues(document.ajaxSearch), fnWhenDone);

·         Edit xml_getPrdInfo.asp

o   Around line 64 there are 11 “include” tags and 2 more further down the code. 
Change all of these to point to your “productcart/includes” or “productcart/pc” folders, respectively.

o   Locate:
tmpList=tmpList & "<img src=""catalog/" & pSmimageURL & """ >" & vbcrlf

o   Edit the above statement as follows:
tmpList=tmpList & "<img src=""/productcart /pc/catalog/" & pSmimageURL & """ >" & vbcrlf

I implemented this on two sites this morning and believe I have covered all of the necessary changes.  If you locate any oversights, please post them so that others can benefit and I'll update the WIKI.
