Significance of a using colon in Joomla URL

问题:

I need to know, if joomla gives any significance to a colon in within component or view?

Is there something in this naming convention?

The colon is only used in the 'id' parameter to separate the numeric id from the slug used for SEF URLs. With view & component names you should not use any colons.

Eg: Non-sef URL - /index.php?option=com_content&view=article&id=45:my-article-title
Sef URL - /my-article-title.html

Also when actually using the id, you should only use the numeric part, which can be extracted using JRequest::getInt('id') in your code.
