-<!-- This page can create whatever iframe structure you want, across whatever
-sites you want. This is useful for testing site isolation.
-
-Example usage in a browsertest, explained:
-
- GURL url =
- test_server()->GetURL("a.com", "/cross_site_iframe_factory.html?a(b(c,d))");
-
-When you navigate to the above URL, the outer document (on a.com) will create a
-single iframe:
-
- <iframe src="http://b.com:1234/cross_site_iframe_factory.html?b(c(),d())">
-
-Inside of which, then, are created the two leaf iframes:
-
- <iframe src="http://c.com:1234/cross_site_iframe_factory.html?c()">
- <iframe src="http://d.com:1234/cross_site_iframe_factory.html?d()">
-
-To make this page work, your browsertest needs a MockHostResolver, like:
-
- void SetUpOnMainThread() override {
- host_resolver()->AddRule("*", "127.0.0.1");
- ASSERT_TRUE(embedded_test_server()->InitializeAndWaitUntilReady());
- }
-
-You can play around with the arguments by loading this page via file://, but
-you probably won't get the same process behavior as if you loaded via http. -->
