We're using DotNetNuke as an internal documentation portal of sorts.  We have a proxy in front of it that perform URL rewriting.  All seemed great until we started hitting some of the more advanced parts of DNN that use AJAX calls.

Here's what is happening:

On a page with an AJAX call we get this error in IE and Firefox (although Firefox hides it in the error log by default):

Error: Sys.ScriptLoadFailedException: The script 'https://sub.contoso.com/DNNPortal/Resources/Shared/scripts/initWidgets.js' could not be loaded.
Source File: https://sub.contoso.com/2c572b4a1c6/portal1/DNNPortal/ScriptResource.axd?d=7Ja4_b1r8R8SA6876VUaxlxngSbOaU6DVT-HnP_QutYki_9pdYEh9cZDCHFf7-TVaxtq6F0x6XsYZ2O-pXaiGwlajQaaIFp30&t=ffffffffec2d9970
Line: 5


The URL that it claims couldn't be found actually hits and redirects perfectly when using a browser to address it directly.

Using fiddler to review the traffic I can see that the page call itself never ends up with a 200 status though, the traffic is a simple 1-2.

HTTP/1.1 302 Object Moved - https://sub.contoso.com/DNNPortal/Resources/Shared/scripts/initWidgets.js

HTTP/1.1 304 Not Modified - https://sub.contoso.com/2c572b4a1c6/portal1/DNNPortal//Resources/Shared/scripts/widgets.js

I'm assuming the browser/javascript engine is erroring on a not-found because of the 304 status that is returned instead of a 200 status.  Is there anything that can be done with DNN to support redirects of this sort?  Perhaps a configuration for AJAX that send the intended outside URL to the browser and avoid the redirect all together?

Yes, Zachary ~  If you would not mind creating an issue in our issue log at support.dotnetnuke.com, that would be great.  This is the log we use to address items in each maintenance release.

Thank you!

I think that will do it - thanks!
The file I ended up with is in a slightly different order but I guess that could be due to slight version differences.  All the content appears the same to me though.

For your reference here is my final script

if (typeof ($dnn) === "undefined") {
    $dnn = new Object();
    $dnn.pageScripts = document.getElementsByTagName("script");
    $dnn.scriptUrl = $dnn.pageScripts[$dnn.pageScripts.length - 1].src;
    $dnn.hostUrl = (typeof ($dnn.hostUrl) == "undefined" ? $dnn.scriptUrl.toLowerCase().replace("resources/shared/scripts/initwidgets.js", "") : $dnn.hostUrl);
    if (!$dnn.hostUrl.endsWith("/")) $dnn.hostUrl += "/";
    $dnn.baseDnnScriptUrl = $dnn.hostUrl + "Resources/Shared/scripts/";
    $dnn.baseResourcesUrl = $dnn.hostUrl + "Resources/";
}

// jQuery dependency
if (typeof (Sys) === "undefined")
    jQuery.getScript($dnn.baseDnnScriptUrl + "MSAJAX/MicrosoftAjax.js", loadWidgets());
else
    loadWidgets();

function loadWidgets()
{
    if (typeof (DotNetNuke) === "undefined")
        Type.registerNamespace("DotNetNuke.UI.WebControls");

    if (typeof (DotNetNuke.UI.WebControls.Utility) === "undefined")
        jQuery.getScript($dnn.baseResourcesUrl + "Shared/scripts/DotNetNukeAjaxShared.js",
                    function() { jQuery.getScript($dnn.baseResourcesUrl + "Shared/scripts/widgets.js"); });
    else
        jQuery.getScript($dnn.baseResourcesUrl + "Shared/scripts/widgets.js");
}

if( Sys && Sys.Application ){
   Sys.Application.notifyScriptLoaded();
}

Thanks again for getting it submitted and tested.   DNN has been great for us and now it can continue saving us from Sharepoint :)
