I don't acknowledge this. I tested this with Windows XPsp1 running IE 6.0.2800 with latest patches. Running on the latest build of Apache server on the same box. IE knew the difference between 'web-inf..' And 'web-inf.' and 'web-inf...' (so did apache). Matter of a fact creating separate pages with these names resulted in separate loading. Perhaps your 'claim' can be further substatiated by what 'you' are doing to IE to cause this.
