How does magento parse url?

Question

We used django and in django there is one file urls.py which mention all possible url patterns. So we just want to know that when i open url http://localhost/magento/index.php/test123.html how this will map to product and which file i can check for this.

Answer 1

Magento has more than one way of matching URLs. modules can register their own patterns, and these will generally be of the form /module/controller/action

In addition, CMS pages have URL identifiers and these can be anything you like - they can contain /s to give the illusion of hierarchy, but they're not significant.

Finally, Categories and Products have URL identifiers and there's a whole table of URL rewrites that map a path (/[category]/[subcategory]/[product] for example) to a product. In your example, I would guess that the product's URL identifier is 'test123' and that the store is setup to suffix URLs with '.html'

So, there's no file to look in (in this case), but rather the database/admin area.
