The URL will be unique for the map as it is generated each time it  
changes. Now if it does
not change, then it will used a cached version of it. IE is well  
known to have had issue with
caching in the past, but this sounds pretty bad. Can you change your  
settings to reload the
page every time and ignore the cache in IE?

Apache should have nothing to do with the problem unless you have  
some special modules
turned on. Apache will just send the map when requested. Do you have  
any proxy or cache
modules active in Apache? Can you turn them off and try it again?
