ASP: URL Rewrite and IIS7

Tweet

Following a kind suggestion by a follower, today we are going to see how to use IIS URL Rewrite 2.0 for IIS 7.

First of all, what's URL Rewrite?

"IIS URL Rewrite 2.0 enables Web administrators to create powerful rules to implement URLs that are easier for users to remember and easier for search engines to find. By using rule templates, rewrite maps, .NET providers, and other functionality integrated into IIS Manager, Web administrators can easily set up rules to define URL rewriting behavior based on HTTP headers, HTTP response or request headers, IIS server variables, and even complex programmatic rules. In addition, Web administrators can perform redirects, send custom responses, or stop HTTP requests based on the logic expressed in the rewrite rules."

Rest assured, we can use it for a classic ASP site as well.
What we need to do is:
1) install URL Rewrite after downloading it from the Ms IIS site;
2) enable ASP.NET role service on IIS 7;
3) write a rule

JavaScript: validate an URL

I've already posted an article on how to validate forms with Regular Expression. But, have you ever needed to valid an URL?
We can do it quite easily using Regular Expressions and JavaScript. Specifically we are going to use the .test method.

The code
The first thing we need to do is set two variables: one is the URL to be validated, the second is the Regular Expression.

<script type="text/javascript">
var url = "http://www.google.com/";
var urlCheck = /^http:\/\/(www\.)?[a-zA-Z0-9-]{3,}\.[a-zA-Z]{2,}(\/)?$/;

JavaScript: validate forms with Regular Expressions (RegEx)

I know I've been posting a lot on forms and validation recently, however we should all agree on the fact that form validation is really a serious problem for programmers.

When a user submit data to our database, the first thing we should consider is to protect the destination. Our database is waiting for specific data and, for example, a text string must not be submitted to a smalldate field.
On the other hand, we should provide a complete and efficient way to help the user in filling in the form. Specifically in commercial situations, if we want the visitors to conclude painlessly a commercial transaction, we should make things the easiest possible way for him/her.

When we check what the user is submitting, we can be sure that the birth date or the credit card expiration date is truly a valid date - for the user protection and security and for the web site owner who needs to be sure that everything works smoothly.

In the following example, we are going to validate emails, however, by changing the regular expression, we can check almost anything.
In the following example we use RegEx in a short JavaScript function.
