It is possible that the browser is caching your previous search (though you obviously don't want it to). Search the archives and look for my MIMEHeaders.inc file and add that to your pages, ala [INCLUDE file=^MIMEHeaders.inc&includes=0]which should stop any flavor of browser from caching the page.> > I have checked to see if I refer to the db in two different ways (per > some discussion in the archives), but it is always referred to as > relative (in the same folder as the templates). > > There's also something funny going on with carts hanging around in my > browser cache. command=Newcart doesn't make a new one, nor does > specifying [cart] in the template, when none was passed, make a new > one. Hitting Reload does kick in a new cart. God what a mess.command=newcart is deprecated (note from the docs): This command is no longer supported as of Version 4.0.Get used to not using it. This also sounds like your browser is getting in the way here as well. See if the MIMEHeaders include file fixes it too. Any time that hitting Reload changes anything (except if you are using embedded contexts in the page) is a sure sign of caching issues.HTHJohn-- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4720 Boston Way Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5747------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
