How Does TrafficCompressor Work?

On-the-fly Traffic Compression.

TrafficCompressor compresses data received and sent over the Internet. When you open a web page or receive an e-mail with TrafficCompressor the data is not transferred directly from the web or e-mail server to your computer. The data is transferred through one of the TrafficCompressor servers located on high-speed Internet backbones. The TrafficCompressor server compresses the data and sends it in compressed form to your computer via your dial-up, GPRS, or other connection. That results in your Internet traffic decrease. This has a side effect - the data is transferred faster.
The TrafficCompressor program running locally on your computer receives the compressed data, decompresses, and delivers it to your web browser, e-mail client, or other local software.

Unsupported traffic (ZIP, MP3, EXE files, FTP, HTTPS, SMTP traffic and so on) is not transferred through the TrafficCompressor servers and not compressed.

Let's examine in details how it works when you are opening, for example, http://www.google.com page in your web browser.

1. You are typing www.google.com address in the address bar of your web browser.
2. TrafficCompressor is sending the web page request to the TrafficCompressor server.
3. TrafficCompressor server is downloading the page from www.google.com web server.
4. TrafficCompressor server is compressing the page and sending it to your computer.
5. TrafficCompressor program is receiving the page, decompressing, and delivering it to the web browser.

The process is similar when you receive/download some other kinds of data from the Internet or when you send/upload something.

	Uncompressed traffic.
	Compressed traffic over your GPRS, ADSL or other connection.
	Unsupported traffic (ZIP, MP3, EXE files, FTP, HTTPS, SMTP traffic and so on) is transferred directly to or from an Internet server without TrafficCompressor.
