Asp Forum - XHR and 12031 - comp.lang.javascript

If I make an XHR call to
[server]/projects/test
IIS returns "HTTP/1.1 405 Method Not Allowed" even though I've edited
the handler mappings to allow "all" verbs to file or folder.

All the files are on the same server.

If set IIS to do a URL rewrite to temporarily add a trail slash so that
[server]/projects/test
becomes
[server]/projects/test/
then every browser I test will allow the XHR call to complete (return a
status of 200). Except for IE.

When I check the developer panel in IE 9 the network pane shows the
request as pending until it finally returns 12031.

When I check the developer panel in IE 10 the debug pane shows "access
is denied" when it tries to XHR open
xhr.open(cfg.method, url, async);

If I put the full URL in
xhr.open(cfg.method, "[server]/projects/test/default.asp", async);
then IE allows the XHR call to complete (return a status of 200).

How do I get IE to behave without needing a full URL?

I cleared the cache, cookies... and now IE 10 misbehaves the same as IE 9.

This implies that you are not making either a GET or a POST request.

Irrelevant. The *URI* scheme, host name, and server-side port number of the
resource to be accessed matter.

Server-side URL rewrite is AFAIK not visible to the client. If the URI
basically works, the former cannot be the reason for XHR failure. However,
that you are using a different URI then may be, because of client-side
caching.

I do not think, especially now that you have discovered that the behavior is
not limited to IE 10, that it matters whether you provide a URI or a URI-
reference (there is no â??full URLâ?, see RFC 3986).

You need to provide the *full* context. A public testcase would be best,
but a more detailed description and screenshots might suffice.

Thanks, that got me thinking and I found that the IIS URL Rewrite
module's action set to redirect. When I changed the action to a rewrite
it started behaving in IE. Why every browser and OS I tested on earlier
"worked" except for IE I don't know.
