Re: [Archive-access-discuss] Absolute path and relative path solution

[Bradley T. <br...@ar...>]

Hi Pramila,

I didn't yet have a chance to respond to your previous post about 
javascript menus. Is this the situation you're facing?

Can you provide some example URLs, or HTML + JS snippets to help clarify 
the situation?

Some background - there are 3 types of URLs:

1) absolute (ex, "http://www.example.org/images/foo.gif")
2) server relative (ex, "/images/foo.gif")
3) path relative (ex, "../images/foo.gif", "images/foo.gif")

Wayback attempts to rewrite all URLs found in HTML. It attempts to 
rewrite absolute URLs found in javascript and CSS.

This leaves server-relative and path-relative URLs.

Path relative URLs should require no rewriting (unless they include 
../../../../ references which back up beyond the actual server root...):

Page: http://wayback.example.com/20010101000000/http://www.example.org/
Containing: "images/foo.gif"
Resolves to 
"http://wayback.example.com/20010101000000/http://www.example.org/images/foo.gif"

which is correct.

Server-relative links do not go to the right place:
Page: http://wayback.example.com/20010101000000/http://www.example.org/
Containing: "/images/foo.gif"
Resolves to "http://wayback.example.com/images/foo.gif"

which is *not* correct.

Wayback does include a server-relative redirection handler. This notices 
incoming URLs like:

"/images/foo.gif"

and uses the "Referer" HTTP request header to correctly resolve the URL, 
redirecting the request back to the correct:

"http://wayback.example.com/20010101000000/http://www.example.org/images/foo.gif"

Note that this requires some specific configuration choices, most 
importantly, Wayback must be deployed at the ROOT context.

Unless Wayback is run at the ROOT context, it will not have an 
opportunity to handle the stray server-relative requests to bounce them 
back on track.

I'm guessing this is the issue you're seeing, but I might be 
misinterpreting your question.
