           Summary: <form> tags used without action attribute but with a
                    <base> tag
           Product: WebKit
           Version: 523.x (Safari 3)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Forms
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: rsesek at bluestatic.org


When a HTML document has <base> tag, all relative URIs should be resolved in
regards to that (as per the W3 spec on the matter:
http://www.w3.org/TR/html401/struct/links.html#h-12.4). However, the handling
of <form> elements without an "action" attribute is incorrect (when using
Firefox and the HTML spec as references).

If you were to use a <form> tag without an action attribute alongside a <base>
tag, then the form will submit to *only* to the href of the <base> tag.
Normally, when a <form> tag does not have an action attribute and a <base> tag
is not present, the form submits to the originating page.

Thus, the logical behavior should be as follows: when a <form> tag does not
have an action attribute and a <base> tag is present, then the form should
submit to the href of the <base> tag concatenated by the originating page.

Example:

Base Tag: http://example.com/base/
Originating page: foo.php

Current implementation would submit to: http://example.com/base/
Fixing this bug would result in submitting to: http://example.com/base/foo.php
