I notice a comment in the code:

     # Note that in HTTP/1.1 the Cache-Control headers override the Expires
     # headers and HTTP/1.0 ignores headers it does not recognize (e.g,
     # Cache-Control). Mulitple Cache-Control directives are split into
     # mulitple headers to better support MSIE 4.x.

What effect does merging the Cache-Control headers have on IE4?
