wget & mod_gzip

wget & curl are very good command line tools to test and pretend to be any browser. Here I’m testing Google webservers and support for content compression.

# pretend to be Firefox 1.5
wget –server-response –user-agent “Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5″ –header=”Accept-Encoding: gzip, deflate” http://www.google.com

# pretend to be IE6
wget –server-response –user-agent “Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)” –header=”Accept-Encoding: gzip, deflate” http://www.google.com

Testing Google JavaScript Compression
wget –server-response –user-agent “Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)” –header=”Accept-Encoding: gzip, deflate” http://www.google-analytics.com/urchin.js

wget –server-response –user-agent “Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)” –header=”Accept-Encoding: gzip, deflate” http://pagead2.googlesyndication.com/pagead/show_ads.js
