Do not block document.written scripts in page reloads

third_party/WebKit/LayoutTests/http/tests/loading/resources/test-reload.js

+// This script sets the flags for blocking doc.write script and then tests the
+// same for first load and for reload.

Now that both tests are in this one js file, can you move this code back into
the html file?

done.

+if (window.internals) {
+    internals.settings.setDisallowFetchForDocWrittenScriptsInMainFrameOnSlowConnections(true);
+    internals.setNetworkStateNotifierTestOnly(true);
+    internals.setNetworkConnectionInfo('cellular2g', 1.0);
+    internals.evictAllResources();
+
+    window.addEventListener('beforeunload', function() {
+        internals.settings.setDisallowFetchForDocWrittenScriptsInMainFrameOnSlowConnections(false);
+        internals.setNetworkStateNotifierTestOnly(false);
+        // Remove localStorage items , just in case they haven't been
+        // already removed due to test failure.
+        window.localStorage.removeItem("blocked-on-first-load");
+        window.localStorage.removeItem("successful-on-first-reload");
+    }, false);
+}
+
+var crossOrigin = 'http://localhost:8000';
+var filePath = '/loading/resources/js-loaded.js?10';

if you need each test to have a cache query, you might consider user the test's
name

Good idea. Modified existing tests as well.

+
+// First time the script will be blocked and onError will reload the page.
+// On reload the script should not be blocked and thus the subsequent
+// asserts in the calling html page will be true.
+// forceReload with true sets the reload to bypass the cache while false
+// sets the reload to use the cache.
+src = crossOrigin + filePath;
+document.write('<scr' + 'ipt src="' + src + '" onload="succTest()" onError="errTest()"></scr' + 'ipt>');
+
+function succTest() {
+    if (window.localStorage.getItem("blocked-on-first-load") == "true") {
+        window.localStorage.removeItem("blocked-on-first-load");
+        window.localStorage.setItem("successful-on-first-reload", "true")
+        internals.forceReload(true);
+    }
+
+    else if (window.localStorage.getItem("successful-on-first-reload") == "true") {
+        window.localStorage.removeItem("successful-on-first-reload");
+        reloadTestSuccess=true;
+    }
+}
+
+function errTest() {
+    window.localStorage.setItem("blocked-on-first-load", "true")
+    if (window.internals) {
+        internals.forceReload(false);
+    }
+}
