post vs get

Get requests have a limit of 2048 characters for Internet Explorer. The get request consists of the URL of the application and the form data.
When security of the data is important (eg. passwords) post is more secure. The data sent by get is visible in the URL and therefore can be viewed in the browser history or in bookmarks.
Since transmission is a single-step process in get, it is faster than post.
Get results can be bookmarked and get applications can be invoked from links (the <a> tag).
