Topic: Apache, relative URLs, and ../

[daivddd]

I'm learning about relative URLs in HTML on my Apache server. I'm able to pull up sites at the localhost fine. I'm now learning about <img src...> and I'm having trouble with ../ to reach an image at a relatively higher directory. localhost is C:\Apache Software Foundation\Apache2.2\htdocs.

I first put the image into the htdocs folder alongside index.html and it's retrieved OK at localhost/index.html with <img src="image.jpg">. I thought that by using ../ I could then retrieve the file at the Apache2.2 directory, but it doesn't seem to work. I can move the image to every directory above htdocs and keep the <img> tag the same at <img src="image.jpg> and I can retrieve the image each time. Also if I stack ../ together without moving the image I can still retrieve it just fine. It's the same whether I use localhost or literal directory names.

What about Apache, relative URLs, and ../ don't I understand?

URLs are relative to the DocumentRoot but for security reasons cannot go above the DocumentRoot.

1st paragraph says as much but it also explains options for getting around it.
