Installation

1. Download and install libecap Library

Download and unpack latest libecap library from: http://www.e-cap.org/Downloads (or use local mirror of version 0.0.3)

wget http://www.measurement-factory.com/tmp/ecap/libecap-0.0.3.tar.gz
tar xvfz libecap-0.0.3.tar.gz

Build and install libecap library:

cd libecap-0.0.3/
./configure
make
make install

2. Download and install VIGOS eCAP GZIP Adapter

Download and unpack latest VIGOS eCAP GZIP adapter from here

wget http://squid-ecap-gzip.googlecode.com/files/squid-ecap-gzip-1.3.0.tar.gz
tar xvfz squid-ecap-gzip-1.3.0.tar.gz

Build and install VIGOS eCAP GZIP adapter:

cd squid-ecap-gzip/
./configure
make
make install

3. Download and install SQUID proxy cache, version 3.1+

Important: The eCAP feature is only available in SQUID version 3.1 or higher. You cannot use the VIGOS eCAP GZIP adapter with earlier versions of SQUID (e.g. 2.6, 2.7, 3.0).

Download and unpack latest SQUID version from http://www.squid-cache.org/Versions/v3/3.1/

wget http://www.squid-cache.org/Versions/v3/3.1/squid-3.1.11.tar.gz
tar xvfz squid-3.1.11.tar.gz

Configure, build and install SQUID:

cd squid-3.1.11/
./configure --enable-ecap
make
make install

4. Configure SQUID to use VIGOS eCAP GZIP Adapter

Add or edit the following lines in your etc/squid.conf:

ecap_enable on
ecap_service gzip_service respmod_precache 0 ecap://www.vigos.com/ecap_gzip
loadable_modules /usr/local/lib/ecap_adapter_gzip.so
acl GZIP_HTTP_STATUS http_status 200
adaptation_access gzip_service allow GZIP_HTTP_STATUS

Now, after (re-)starting SQUID, all text/html responses from clients sending the Accept-encoding: gzip HTTP header will be compressed.

If you get a problem compiling libecap edit the file libecap-0.0.2/src/libecap/common/name.cc

change the line

#include <limits>

#include <climits>

it's a bug: https://bugs.launchpad.net/ecap/+bug/327417

I need to install clamav in order to be able to "make" VIGOS eCAP GZIP Adapter: apt-get install clamav

Is it possible to enable compression for other content than text/html, e.g., text/xml, javascript, css, etc.?
