ah yes, I remember the nokeepalive thing.  We used that too.  However,  
we ran into some problems with it, although I can't recall what...  
this was a couple years ago.  It may have had to do with large  
attachments causing the "page cannot be displayed" or something  
similar.  There were definitely consequences to having no keep alives  
in IE.  We ended up taking it back out, and fixing the problem by  
adjusting apache settings.  But, if it's working for you, then alls  
well that ends well!
