Oops, sorry... seems I was barking up the wrong tree! The true issue was something unrelated.

Enabling Cross-domain Posting for a Classic ASP Website

Hi,

We've migrated a number of old sites we've inherited across to IIS7 / Windows Server 2008, however we've run in to an issue which I believe is possibly IIS7 being locked down by default to deny cross domain form posts.

domainA.com has a link which when clicked posts a form with a hidden field to domainB.com. But when this is clicked a 500 - Internal server error is encountered.

The form:

<a onclick="document.forms['suppliers'].submit();" href="#">Supplier Directory</a>

</form>

I've come across a number of solution for silverlight / ASP.NET web service centred solutions which use clientaccesspolicy.xml / crossdomain.xml to allow cross domain access, but these don't seem to work in our case.

Any gurus out there with any suggestions?

Cheers,

Gavin

IIS7 - Classic ASP
