Uniform Resource Locators (URLs) Explained

This section provides additional information about what URLs are and how URL Manager Pro handles them.

Syntax of URLs
A Uniform Resource Locator (URL) is the format in which an Internet address is stored.

It takes the format:

     <protocol> <username> <password> <hostname><port> <path> <document>

For example, the URL of this document could be:

     http://www.url-manager.com/doc/manual.pdf where

     http:// is the protocol indicating the URL is the address of a Web page,

     www.url-manager.com is the name of the host computer,

     /doc/ is the path (also called a subdirectory) on that computer, and

     manual.pdf is the name of the document.

The URL of a password-protected page looks like this:

     http://myfriends:secret@www.address.edu/index.html

Note: username, password, path and document are optional elements of a URL; some URLs only consist of prefix and hostname. Others are just a path and document. A document can also be a program, such as a Perl script.

URLs were originally intended for internal use by Internet programs, not to be seen by end-users. As a result, they are not particularly "user-friendly." They can be long and arcane looking.

URL Manager Pro and URLs
URL Manager Pro does it best to shield you from complexity of URLs by representing them by icons and allowing you to give them a descriptive label. It allows you access and manipulate URLs by convenient techniques, such as pull-down menus and as Drag & Drop. We recommend that you do not edit URLs manually. If you make an error in a URL, it will no longer work. Errors in URLs are difficult to fix, and it may take you considerable effort to relocate the Web page or E-mail address whose URL you lost.

However, if you are an experienced user, you will find that URL Manager Pro enables you to view and edit URLs very easily.

Types of URLs
By far, the most frequent URLs you will save in URL Manager Pro will be Web pages. However, URL Manager Pro also recognises other types of URLs. These are: Web addresses, E-mail addresses, FTP hosts, Newsgroup addresses, Telnet hosts, Finger hosts, Gopher addresses, Wais hosts, Query URLs

Based on its protocol, each type of URL in URL Manager Pro has been assigned a default Internet application. This application is opened when you select a URL of this type.

To know which assignments to use, URL Manager Pro uses the information stored on the Internet tab of its Preferences Window. You can view and modify your Web browser and E-mail program assignments by selecting the Preferences command of the Edit menu or by clicking the Pref button in the Toolbar of URL Manager Pro. Then go to the Internet tab of its Preferences Window.

You can modify other assignments in Internet Config by selecting Launch Internet Config on the Preferences submenu of the Edit menu in URL Manager Pro. However, on Mac OS 8.5, you use the Internet Control Panel.

Open the Internet Control Panel.

Select the User Mode command from the Edit menu.

Click the Advanced tab.

Click the icon Helper Apps in the left icon scroll box.

Modify your assignment in the Helper Application Assignments box.

Bookmarks and URLs in URL Manager Pro
URL Manager Pro uses the concept "Bookmark" in its handling of URLs. In URL Manager Pro, a Bookmark is comprised of a URL, a user-defined Name, an optional Note, and several attributes. This information can be viewed and modified in the Get Info Window.
