This sould be a simple task. All you have to set in the request structure is 
the following:

	request->method = METHOD_HEAD;
	request->output_format = WWW_MIME;

WWW_MIME doesn't really make sense - it's just an internal repressentation 
meaning that the MIME headers should be kept. You can see an example in Line 
Mode Browser using:

	www -head -o <local.file> http://www.w3.org

if you want the whole content plus MIME headers then use

	www -to www/mime -o <local.file> http://www.w3.org

(the code can be found in HTBrowse.c in the LineMode/Implementation directory)
