Resources such as JavaScript and CSS files can be compressed before being sent to the browser, improving network efficiencies and application load time in certain case. If you are not using Apache with mod_deflate or nginx in front of your web application, you may need to implement resources compression yourself….

Wait! don’t start writing your own filter to compress files like CSS, html, txt, javascript it is way more difficult than you think to properly handle http response headers and do proper handling of mime type and caching. In one sentence don’t start reinventing the wheel: use ehcache for example.

Ehcache is an open source, standards-based cache used to boost performance, offload the database and simplify scalability. Ehcache is robust, proven and full-featured and this has made it the most widely-used Java-based cache. It can scale from in-process with one or more nodes through to a mixed in-process/out-of-process configuration with terabyte-sized caches. For applications needing a coherent distributed cache, Ehcache uses the open source Terracotta Sever Array.

Official version of nginx for Ubuntu Precise is 1.1.19 but the latest available stable version is 1.2.2 (Changes), In this post I will present you how to update to the latest available version.

vi /etc/apt/sources.list

and add depending on your Ubuntu version either

For Ubuntu 10.04 Lucid:

deb http://nginx.org/packages/ubuntu/ lucid nginx
deb-src http://nginx.org/packages/ubuntu/ lucid nginx

For Ubuntu 12.04 Precise:

deb http://nginx.org/packages/ubuntu/ precise nginx
deb-src http://nginx.org/packages/ubuntu/ precise nginx

Now you can run

apt-get update

When using the public nginx repository for Ubuntu, you’ll get this error

W: GPG error: http://nginx.org lucid Release: The following signatures 
couldn't be verified because the public key is not available: NO_PUBKEY ABF5BD827BD9BF62

First of all this is only warning and you can ignore it, if you know what are you doing and in case you prefer to add public key, used for signing packages and repository, just run:

gpg -a --export 7BD9BF62 |  sudo apt-key add -

or

wget http://nginx.org/packages/keys/nginx_signing.key
cat nginx_signing.key | sudo apt-key add -

apt-get update should now run fine, however after running an

apt-get install nginx

you may still get this kind of error:

dpkg: error processing /var/cache/apt/archives/nginx_1.2.2-1~precise_amd64.deb (--unpack):
 trying to overwrite '/etc/logrotate.d/nginx', which is also in package nginx-common 1.1.19-1
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
Errors were encountered while processing:
 /var/cache/apt/archives/nginx_1.2.2-1~precise_amd64.deb

just remove nginx-common and retry

apt-get remove nginx-common

nginx (pronounced “engine-x”) is an open source Web server and a reverse proxy server for HTTP, SMTP, POP3 and IMAP protocols, with a strong focus on high concurrency, performance and low memory usage. It is licensed under a BSD-like license and it runs on Unix, Linux, BSD variants, Mac OS X, Solaris, AIX and Microsoft Windows [WikiPedia]

Instructs proxy servers to cache two versions of the resource: one compressed, and one uncompressed. This helps avoid issues with public proxies that do not detect the presence of a Content-Encoding header properly.

Configuration files are provided using Gist  https://gist.github.com/1620307 and are CONSTANTLY updated for added security and speed. Gist is a simple way to share snippets and pastes with others. All gists are git repositories, so they are automatically versioned, forkable and usable as a git repository. I recommend you to starred them to stay up to date.
