CHAPTER 6. USING EXTERNAL RESOURCES 67
If (1) is our absolute address, and (2) is the docroot address, then (3) is the
matching absolute address.
(1)http://example.com/abc/def/ghi/index.html
(2)/pqr/photo.jpg
(3)http://example.com/pqr/photo.jpg
In this case, because (2) starts with a slash, we throw away the entire path
from (1), leaving us with just the domain name. Then we add the path from
(2) giving us the result in (3).
6.9 img src=...
When creating an image (img) tag, the source (src) must be specified. It can
be (R) relative, (D) docroot, or (A) absolute. (L) local is a form of absolute,
but it is only visible on the original computer. The file is not online.
(R)
- relative
(D)
- docroot
(A)
- absolute
(L)
- local
6.10 a href=...
When creating an anchor (a) tag, the http reference (href) must be specified.
It can be (R) relative, (D) docroot, or (A) absolute. Again, (L) local is a
form of absolute, but it is only visible on the original computer. The linked
webpage is not online.
(R)- relative
(D)- docroot
(A)- absolute
