Can you tell me the difference between "application/zip" and "x-zip-compressed"?

Note: Also which is one is legacy (if applicable) and if there is any issue with IE6,7,8

I am using Response.TransmitFile to send a zip to the client browser and I notice that some sample code on web uses one or the other as the value for Response.ContentType property.

Dear EE member,
IE4 onwards supports x-zip-compressed
check HKEY_CLASSES_ROOT\MIME\Database\Content Type

I had to research on application/x-zip-compressed, since it is a non-standard MIME.

http://www.mimeapplication.org/

"The mime application/x-zip-compressed content type is a non-standard MIME type. This means that the Internet Assigned Names Authority has not registered the MIME type and its use is not standardized. Zip files are compressed archives containing other files."

x-zip-compressed is more common in these days. See "IE4 onwards" quoted above.

Again, what is the difference/advantages between them?
if it is more common why? If it is non-standard MIME, does it mean it is not supported on every OS?
yjchong514: I have already had a working system, I am just curious about why people use either one of this context types and if there is any limitation about them that I need to be aware of.

I believe that they are similar, and that there isn't much difference between the two, other than the late adoption of the x-zip-compressed type.  I believe that application/zip is definitely more common in my world, but x-zip-compressed will still be processed by browsers.  I couldn't find references to confirm that for all browser types.  I always stick to the application/zip MIME type, so this was an interesting question from the research standpoint.
