When debugging a customer who couldn't load our site with an http
connection (worked fine on ssl as it bypassed the firewall) we came
across an issue where if we tried to load the *.cache.html file gwt
was trying to load manually the companies firewall had displayed an
error message. There was no error on the gwt side, so we were unable
to provide feedback to the user.
Is it possible to write something in the nocache.js that checks that
the *.cache.html that is loaded is actually what we expect, and if
not, we can get an error message back to the user in some way?
Currently we use the following method for detecting load errors, but
they aren't being called. Could it be tied into this in some way?
<meta name="gwt:onLoadErrorFn" content="loaderror"></meta>
<meta name="gwt:onPropertyErrorFn" content="unsupported"></meta>
<script type="text/javascript">
<!--
// Called when GWT is not supported
function unsupported() {
document.getElementById('loading').className =
"loadError
message-center-screen";
document.getElementById('loading-content').innerHTML = "Your
browser is not supported. Please reload with a modern browser such as
<a href=\"http://www.getfirefox.com\";>Firefox</a> or Internet Explorer
Version 6 or Above.";
}
function loaderror(){
document.getElementById('loading').className =
"loadError message-
center-screen";
document.getElementById('loading-content').innerHTML = "Error:
There was a problem loading the application.";
}
-->
</script>
E.g. a new meta property could be added that tells us the cache file
is not able to be loaded, with the name of the cache file so we can
show them the error by opening it in a new window so they can see the
error message.
