Uniform Resource Identifier

Uniform Resource Identifier (URI)

Internet resource locators, described in RFC 1736, convey location and access information for resources. Typical examples of resources include network accessible documents, WAIS databases, FTP servers, and Telnet destinations. Locators may apply to resources that are not always or not ever network accessible.

URL is used to describe the identity of an item. URI provides a technique for defining the identity of an item. URL links a web page, a component of a web page or a program on a web page with the help of accessing methods like protocols. URI is used to distinguish one resource from other regardless of the method used.

The HTTP stands for Hyper Text Transfer Protocol and the URLS stands for Uniform Resource Locator. The URL is the web address of the particular website while the HTTP is the actual resource locator or a server.

It’s actually not necessary to use WWW in URLs. It exists for just one purpose – to identify the address as a website. This is not the case with other important URL signifiers, such as a File Transfer Protocol (FTP) server (ftp) or news server (news). As such, WWW may be classified as a subdomain of a larger website.

A URL usually looks something like this: It (usually, but not always) starts with “http://” or “https://” it is often followed by “www” and then the name of the website you want to visit.

A URL is a Uniform Resource Locator, a tool used to find webpages. A URL is composed of a protocol, a domain name, a path to the webpage, and a webpage name.

WWW vs Non-WWW – Technical Differences A non-www domain is sometimes referred to as a “naked” domain. And, www domains can act as a hostname and can have several subdomains attached to it. From a practical perspective, there is no difference between a www and a non-www URL.

If you must escape a character in a string literal, you must use the dollar sign ($) instead of percent (%); for example, use query=title%20EQ%20″$3CMy title$3E” instead of query=title%20EQ%20’%3CMy title%3E’ ….URL escape codes.

URL-encoding from %00 to %8f

You can use HTTPUtility. URLDecode to remove %20 and any other encoded characters. It won’t actually remove it, but rather, replace it with a space, as that is what it represents. If you actually want it removed completely, you have to use replace.

Use URLEncoder to encode your URL string with special characters….2 Answers

1. The alphanumeric characters “a” through “z”, “A” through “Z” and “0” through “9” remain the same.
2. The special characters “.”, “-“, “*”, and “_” remain the same.
3. The space character ” ” is converted into a plus sign “+”.

So when a URL wants to represent something like a space, it uses %20. It does this so that internet clients like browsers don’t have to deal with special characters like spaces, tabs, and carriage returns.

It’s used to place characters in URLs that aren’t typically allowed. The encoding is a percent sign followed by an ASCII value (in hexadecimal). So %20 is a space, %30 is the number 0, %3b is semicolon and so on.
