Ummm, This output compression sounded cool to me when I came across it, but I wasn't sure it really helped or was appropriate for us to use:
1. My biggest concern is the slowest user i.e. at the end of a modem on the other side of the planet. I thought they would almost certainly have modem compression so doing our own compression doesn't really help them at all i.e. actual download speeds stay the same, it's just we/they do the work rather than the modems. 2. I was surprised when I got ISDN dial-up that it didn't seem to have automatic compression on the line, but assumed that was going to change. Am I too hopeful? 3. But surely, ASDL, cable, the backbone and decent intranets must all do hardware compression, don't they? Or are they secretly not very keen on decreasing network traffic? 4. Finally, if the network hardware isn't handling compression for us, I would have thought it was a good job for a web server. I guess I'd have to ask the Apache guys, but I would guess this can be really neatly done with some fancy mod_rewrite, custom extension or whatever. In summary, I can't agree more that all pages should be compressed, but don't feel it should be our job. Maybe I'm wrong and this is another case of the poor old application developer having to do all the ***** work, just because the rest of the computing industry is too busy counting its profits to do its own job properly ;). What's everyone else think?
