The idea is the same as crossdomain.xml in flash -- content can explicitly opt into being shared across ___domain boundaries. Our real problem is that there's no way to know whether content is generically available to the Internet, or just you because of IP firewalling / cookies / whatnot. So we have to default to blocking all cross ___domain reads, since that other ___domain might be hosting your email. On Sun, Sep 12, 2010 at 7:43 PM, <paul.szabo () sydney edu au> wrote:
One of my users asked me to install MathJax on my server. Reading installation instructions in http://www.mathjax.org/resources/docs/?installation.html#notes-about-shared-installations I came across the following: ... Firefox's same-origin security policy for cross-___domain scripting. Firefox's interpretation of the same-origin policy is more strict than most other browsers, and it affects how fonts are loaded with the @font-face CSS directive. ... There is a solution to this, however, if you manage the server ... create a file called .htaccess that contains the following lines: ... Header set Access-Control-Allow-Origin "*" That would suggest that this same-origin policy can be defeated by settings on the "evil" server: the policy is not enforced, useless. Did I misunderstand something? (Does not really matter to me, am not planning on using that setting, but am wondering about Firefox workings.)
