gzip

gzip is a widely used open source utility for compressing files.

mod_gzip is now configured on our web server to handle .snf files. This means that if your download mechanism (browser or utility) is capable of accepting gzip encoding then you can get your .snf file from the web server much more efficiently.

For example, if you know how to chain gzip into the wget part of your update script then you can save yourself and us a good deal of bandwidth and time. The use of gzip in your rulebase download scripts can reduce the bandwidth required for your download significantly (typically 70% or more!).

Wget w/ gzip Setup instructions:

In the wget command change

-O sniffer.new

to

-O sniffer.new.gz

and add the switch

--header=Accept-Encoding:gzip

and in the next line put the command

gzip -d -f sniffer.new.gz

Of course you will also need to download gzip to make this work if you don't already have it. http://www.gzip.org/
