Content-Length for HEAD when using compression?

[Michael McGlothlin <michaelm@xxxxxxxxxxx>]

I'm using PHP to dynamically serve images and am using compression on 
the output. For GET I know that I should make the Content-Length header 
the size of the compressed data. For HEAD requests do I do the same or 
do I provide the uncompressed Content-Length? Thanks.
