First - I sent an unedited message to the list just now. Sorry. My mailer has just *one* question that does not take return, all the rest do :-P Kee Hinckley wrote: > Which leads me to another question.

Arena (all versions that I have used, from 0.90 onwards) send out Accept: headers based on your .mailcap, but not the system wide mailcap, for example HTTP........ Connected, socket 5 HTTP Tx..... GET /hypertext/WWW/Arena/0.96 HTTP/1.0 Accept: application/x-dvi; q=0.500 Accept: video/*; q=0.500 Accept: video/mpeg; q=0.500 Accept: text/tab-separated-values; q=0.500 Accept: image/x-png; q=0.500 Accept: image/png; q=0.500 Accept: application/applefile; q=0.500 Accept: application/x-metamail-patch; q=0.500 Accept: sun-deskset-message; q=0.500 Accept: mail-file; q=0.500 Accept: default; q=0.500 Accept: postscript-file; q=0.500 Accept: audio-file; q=0.500 Accept: x-sun-attachment; q=0.500 Accept: text/enriched; q=0.500 Accept: text/plain; q=0.500 Accept: text/richtext; q=0.500 Accept: application/andrew-inset; q=0.500 Accept: x-be2; q=0.500 Accept: application/postscript; q=0.500 Accept: message/external-body; q=0.500 Accept: message/partial; q=0.500 Accept: image/x-xwd; q=0.500 Accept: image/*; q=0.500 Accept: audio/basic; q=0.500 Accept: audio/*; q=0.500 Accept: */*; q=0.100 Accept: application/x-compressed; q=0.100 Accept: application/octet-stream; q=0.100 Accept: text/x-html3; q=0.800 Accept: text/html; level=3; q=0.900 Accept: text/html; q=0.600 Accept: image/x-xbitmap; q=0.600 Accept: image/x-xpixmap; q=0.600 Accept: image/jpeg; q=0.600 Accept: image/gif; q=0.600 Accept: text/plain; q=0.400 User-Agent: Arena/0.96s libwww/ Note that there are good quality factors for the HTML formats. I had thought it sent out the stuff from /usr/local/lib/mailcap too, but obviously not; a pity. Notice also the q factor for */* It is difficult to see how a single q factor could effectively resolve a situation with GIF and JPEG both available; JPG is better for many pictures, but GIF is better for some. Ah well, notice I have x-png in there :) There are some wierd and non-standard accept lines in there, because the .mailcap was generated by metamail, which tries to understand sun mailtool stuff as well as MIME. Really I need more granularity than a single file for all applications. -- Chris Lilley +----------------------------------------------------------------------+ |Technical Author, Manchester and North HPC Training & Education Centre| +----------------------------------------------------------------------+ | Computer Graphics Unit, | Email: Chris.Lilley@mcc.ac.uk | | Manchester Computing Centre, | Voice: +44 61 275 6045 | | Oxford Road, Manchester, UK.M13 9PL | Fax: +44 61 275 6040 | +-------------------------------------+ BioMOO: ChrisL | | URI: http://info.mcc.ac.uk/CGU/staff/lilley/lilley.html | +----------------------------------------------------------------------+ | "The first W in WWW will not wait."
