Change data sent using POST method of HTTP

The main HTTP methods used for sending data to the web server are GET and POST method. When using the <strong>GET method</strong>, the data is encoded directly in the requested URL, specifically to the query part of it. The query part starts with a question mark and consists of pairs key, value in a form <code>key=value</code>, the pairs are divided by an ampersand. For instance to inform the web server that a user wants to log off, quite often the URL of the form <code>index.php?action=logout</code> is used. Therefore it is very easy to change the sent data. The <strong>POST method</strong> uses the body of the HTTP message to store the data. The user has no direct possibility to change the data. We want to find an easy way to do so.

Improve accessibility of a website

For differently-abled people it is quite complicated to access content on the Internet. To improve this the W3C consortium issued a recommendation called WCAG - Web Content Accessibility Guidelines. The <a href="http://www.w3.org/TR/WCAG10/">recommendation </a> defines 3 priority levels of the recommendations: [Priority 1] A Web content developer must satisfy this checkpoint. Otherwise, one or more groups will find it impossible to access information in the document. Satisfying this checkpoint is a basic requirement for some groups to be able to use Web documents. [Priority 2] A Web content developer should satisfy this checkpoint. Otherwise, one or more groups will find it difficult to access information in the document. Satisfying this checkpoint will remove significant barriers to accessing Web documents. [Priority 3] A Web content developer may address this checkpoint. Otherwise, one or more groups will find it somewhat difficult to access information in the document. Satisfying this checkpoint will improve access to Web documents. However a lot of websites does not fulfill even the Priority 1 recommendations. We want to find a client-side solution for altering of such pages for the people with special needs.
