Losing session after file uploading

[Bram]

Hello,

We are using DNN 4.8.2 Portal with some subportals. Some of our modules are using Telerik controls to upload files. On the main portal all works fine, but on the subportals we have a problem with Telerik RadProgressManager / RadProgressArea controls.
So you can browse and select a file, view progress bar, but once the upload has completed, session will be lost immediately.  It appears because of some cookies are removed: .DOTNETNUKE, portalaliasid, portalroles. As I mentioned before these cookies will be lost on sub portals only – on the main portal they will still present after upload is finished.  If progress bar is not used everything will works fine.

We are using 2008.1.619.35 version (RadControls_for_ASP.NET_AJAX_2008_1_619_dev.exe).

DNN configuration:

Web.config
<configuration>
…
<location path="Telerik.RadUploadProgressHandler.ashx">
            <system.web>
                        <authorization>
                                   <allow users="*" />
                        </authorization>
            </system.web>
</location>
…
<httpModules>
            …
            <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI" />
</httpModules>
…
<httpHandlers>
…
    <add verb="*" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler, Telerik.Web.UI" /></httpHandlers>
…
</configuration>

SiteUrls.config are:

<?xml version="1.0" encoding="utf-8" ?>
<RewriterConfig>
            <Rules>
                        <RewriterRule>                                       
                                   <LookFor>.*Telerik.RadUploadProgressHandler.ashx(.*)</LookFor>
                                   <SendTo>~/Telerik.RadUploadProgressHandler.ashx$1</SendTo>
                        </RewriterRule>
                        <RewriterRule>
...
</RewriterConfig>


What can cause such behavior? Is it connected to issue http://www.telerik.com/community/forums/thread/b311D-dtgtt.aspx? How it can be fixed?

Hi Jochem Nuij,

Did you modify DNN's URL Rewriter rules?

This should be done by opening the SiteUrls.config file from the DotNetNuke\Website folder in a text editor and add the following before the other <RewriterRule> tags:

<RewriterRule>

<LookFor>.*Telerik.RadUploadProgressHandler.ashx</LookFor>
<SendTo>~/Telerik.RadUploadProgressHandler.ashx</SendTo>

</RewriterRule>

This will allow RadUpload's URLs to be handled properly by DNN's URL Rewriter. Please note, that RadUpload's RewriterRule should be the first one in the list.

Kind regards,

Yes, but unfortunately it didn’t help.

Our SiteUrls.config look like:
<?xml version="1.0" encoding="utf-8" ?>
<RewriterConfig>
            <Rules>
                        <RewriterRule>
                                  <LookFor>.*Telerik.RadUploadProgressHandler.ashx</LookFor>
                                  <SendTo>~/Telerik.RadUploadProgressHandler.ashx</SendTo>
                        </RewriterRule>
                        <RewriterRule>
                                   <LookFor>.*DesktopDefault.aspx(.*)</LookFor>
                                   <SendTo>~/Default.aspx$1</SendTo>
                        </RewriterRule>
                        <RewriterRule>
                                   <LookFor>.*EditModule.aspx(.*)</LookFor>
                                   <SendTo>~/Default.aspx$1</SendTo>
                        </RewriterRule>
                        <RewriterRule>
                                   <LookFor>.*/TabId/(\d+)(.*)/Logoff.aspx</LookFor>
                                   <SendTo>~/Admin/Security/Logoff.aspx?tabid=$1</SendTo>
                        </RewriterRule>
                        <RewriterRule>
                                   <LookFor>.*/TabId/(\d+)(.*)/rss.aspx</LookFor>
                                   <SendTo>~/rss.aspx?TabId=$1</SendTo>
                        </RewriterRule>
                        <RewriterRule>
                                   <LookFor>[^?]*/TabId/(\d+)(.*)</LookFor>
                                   <SendTo>~/Default.aspx?TabId=$1</SendTo>
                        </RewriterRule>
            </Rules>
</RewriterConfig>

I tried to place SiteUrls.config file to DotNetNuke\Website (subportal) folder. But on subportal cookies are still lost.

Hi Jochem,

Not sure if that will help, but you might try the following:

<RewriterRule>
    <LookFor>[^?]*/TabId/(\d+)(.*)Telerik.RadUploadProgressHandler.ashx</LookFor>
    <SendTo>~/Telerik.RadUploadProgressHandler.ashx?TabId=$1</SendTo>
</RewriterRule>

Cheers,

This is more or less the same thing, but if you'd rather handle it in code, this is what worked for us:

Radprogressmanager1.AjaxUrl = Page.ResolveUrl("~/Telerik.RadUploadProgressHandler.ashx") & "?TabId=" & TabId
