Web Hosting Leader:
HTTP Compression Technique Used in Web Hosting Services
The web hosting businesses run on the basis of provisioning of a free web space for their clients. These web spaces are coupled with IP address that makes the provision of a unique identifier for their resources on the World Wide Web. The content that needs to be managed by these web hosting companies so that there can be an optimization of web space is huge. Hence the web hosting companies need to deploy some of the compression techniques in order to run their business. In this article, we are going to pick up one such compression technique viz. HTTP compression and we are going to have a detailed look at how the web hosting companies implement such techniques. HTTP compression is a capability that can be used to integrate with the web servers of the web hosting services. This enables the web hosting companies in order to be better at their traffic management strategies. This is because HTTP compression provides them a chance to make better use of the scarce bandwidth available to them on the internet. They also enable the faster speeds of transmission between the web server and the clients of the web hosting services. The main technique that lies beneath this technology is to compress the HTTP request before it is sent from the client end to the web server. The web browsers used by the clients of the web hosting companies perform the capabilities exchange with the web server in order to make them identify what kind of compression is available for them to decode. The clients who do not have the browsers with compliant HTTP compression schemes will necessarily download the uncompressed data. Most of the compression schemes that govern the HTTP compression on the World Wide Web are Gzip and deflate. The Internet Assigned Numbers Authority (IANA) is in charge of maintenance of the compression schemas that are used by the web browsers all over the world by the web hosting company standards. Additionally, the compression schemas for the HTTP compression techniques are also developed by the third party authorities and include them along with their products. A classic example of a web hosting company with this is Google Sites. Google sites has developed its own compression schema and implemented it in the Google Chrome Web browser. There is a capability exchange mode implemented which decides what is the best HTTP compression method to be utilized by the web server and the web browser. If we exclude the negotiation of the capabilities by the SDH, then we can implement the HTTP compression in two stages. The first stage includes the acceptance of the encoding in the HTTP request. This is couple along with the supported names of the schemas. If it so happens that the web server is also capable of compression the HTTP request as per the compression schemas described by the client end, then the most advanced form of compression schema is implemented for transferring information via HTTP compression. The web server is by no means obligated in order to decide on its own as to which compression scheme to implement. There should be a request of HTTP compression specifically introduced by the web server. Or else the web server will fail to issue an HTTP compression delivery. However, the web hosting companies might modify the default settings by the execution of certain scripts on the web server. Things are different when it comes to the compression schema of SDH. In case of SDH, the dictionary negotiation is also put to use by the web server and the web browser. There should be a proper download implemented for the relevant dictionary from the external server. Related articles
