Every so often recently, a subset of our users report seeing small snippets of page source, such as part of a declaration cut off abruptly, displayed in the middle of the page where you would expect the rendered element to appear instead.
We know these users use IE6 instead of IE7, and have connections that can sometimes be very slow, but we have not been able to reproduce this when trying to replicate their environment.
Why is this happening? Could it be a problem with HTTP compression, which we have recently enabled?
