["paola" <editor@content-wire.com>]

Hi Folks
It seems something worth promoting.
Sorry for not doing this before,  but I have been away (with the mind as
well)
Please someone answeres the following , off list if you wish, and I shall
put it out. If I get more than one reply, I can merge the answers

Cheers

What is rss feed compression

What advantages does it deliver

How is it best implemented?

Can compression be external to the site (ie the feed links to another
website that compresses the feed and produces another compressed feed as
output)

Who has done it already

Where can people get their feeds compressed

Anything else you wish to say, links etc

If you want to support gzip without much work, take a look at this Apache
module...

http://sourceforge.net/projects/mod-gzip/

I also wrote an Apache module years ago that checks for a .gz version of
every static file on the web server, and if the browser accept-encoding:
handles GZ, sends that version. This way the actual compression can be done
by a spider running asynchronously to the web server process (maybe on a
separate machine), and very little extra  extra load is placed on the server
itself (really just the cost of one or two stat() calls for each request). I
haven't released the code but if anyone's interested let me know and I can
put it up somewhere. The new mod_gzip might support that kind of thing
anyway.

I have added a histogram of the compression ratios, expressed
as a percent of the original size:

I am surprised that no one seems to care about this.
Wouldn't it be great to reduce feed traffic to 1/3 of its
old level? We can help to make that happen.
