[Springframework-developer] Re: Plans for mime type in Resource?

[Matt S. <sga...@us...>]

OK, I see what you're getting at now.  The problem is, how do you want 
Spring to figure out the mime type if it's not based on file extension? 
  By dynamically inspecting the contents of the file at runtime?  I know 
that's possible because IE does it, but that seems like it would be a 
pain to implement.  Is there some other approach you could take, like 
storing the mime type information external to the file itself?
