What you should do right before deploying your web site
Web grows fast and delivers the colossal impact in modern life. And many service provider are preparing for web service relating to other industries. If you are one of them, however, you need to check many things before you launch the service. I want to mention three things to check here and will explicate why you should keep each of them in mind.
Validation of Web Standard (W3C Validation)
The main reason of this phase is that many browser vendors have made their programs so differently. Keeping web standard may help your service shown identically regardless of browser environment. W3C, who enacts the web standard offers a service to validate online. (http://validator.w3.org) Insert your site address and click Check button to conduct validation. If you meet some errors or warnings, then you'd better remove them all.
Optimization
Optimization is important to improve the performance of the service. According to the statistics from Amazon.com, 0.1 second speed-up brings 1% revenue increment. There are many subjects about the method so you can research for them. Here is a list of optimizing issues.
- Locating inline script and stylesheet(CSS) properly.
- Deferred script.
- Gzip compression.
- How CSS selector operates in browser.
- Optimization of images (GIF, JPEG, PNG, etc)
Security Manners
It is essential to sanitize user's input. You'll get a big trouble by hackers who targets at the core information in your site unless missing security managing process. That is, the personal data and information could be divulged or manipulated. The range of security is broad but you can see the following issues primarily.
- XSS (Cross-site script) attack.
- SQL injection.
- Intercepting user session.
- Exploiting vulnerabilities of browser.
