Re: why does my browser Window goes white 

Hi Shawn,

What I am saying is that if you want to make absolutely sure you will not have caching related issues after you deploy the application to your production server, then yes, you should follow this every time.

Whether you can get away with less than full cache clearing, depends on several things like for instance the nature of the changes being made with the new version you are deploying.

Again, if you want to make sure, you do the full clearing of cache. If you are ok to save some time and take the chance that your users will not experience any caching related issues, then you may decide to skip it. Somewhere in between is probably the course most users take, depending on for instance if you deploy during full production hours, if you have active users when you deploy or very soon after etc. etc.

Hope this explains,

Palli

Re: why does my browser Window goes white 

Do I have to make sure my users are clearing their browser cache also?  If so, they aren't going to like that very much.

Thanks,

Shawn

Re: why does my browser Window goes white 

Hi Shawn,

Like I said, if you want to make absolutely sure, then yes.

I also said that you may be able to get away with only part of the procedure, depending on the changes and depending on your environment. Most of the time, uppering the privateversion of web.config on the server should be enough, as that will invalidate all client side cache for the application, so users should be refreshed.

However, there are certain type of changes that are not so easy to get refreshed. One I can recall from the back of my head just now is if you want to change the favicon.ico. For some users, they will not get the new favicon.ico file on their application until after they have cleared all cache locally, and in some cases they also have to clear their browser's history.

It all depends on the change...

Palli

Re: why does my browser Window goes white 

I am back working on this problem.

I have just put out a new version of my app onto my production server. As soon as I get this issue resolved the VWG app will be open to our users.  I am using VWG .NetHTML5 6.4.0 beta from May 23,2011.  I have go through the entire clear cache procedure that you outlined in a previous post on this thread.

The issue that I am having is that after logging in (the login form is drawing) by pressing the login button, I see my "main" application screen in the browser for either a split second (before the screen goes back to the login or turns completely white), or on first or second button click it goes back to the login or turns completely white.

I did the debug window and a command TP=MainWindow is firing after the login.

In my main.vb page Main_Load()  I am using the following so that each browser tab is a different session.  This allows me to have multiple users logged in on the same browser, in different tabs.  This is needed for our support team.

 If Context.HttpContext.Request.QueryString("vwginstance").ToString() = "0" Then
            mInstanceCount += 1
            Dim dcPath As String = String.Empty
            dcPath = dcSession.GetParameterValues("org")
            Gizmox.WebGUI.Forms.VWGContext.Current.Item("DCPath") = dcPath
            Context.Redirect("Main.wgx?vwginstance=" + mInstanceCount.ToString() & dcPath)
            Context.Terminate(True)
            Return
        End If

 

I am also making use of of some vwg session vars

Gizmox.WebGUI.Forms.VWGContext.Current.Item("OrgID")

Gizmox.WebGUI.Forms.VWGContext.Current.Item("UserID")

VWGContext.Current.IsLoggedOn = True

 

I need some direction here on what to do.  This only happens on my produciton II6 server (32bit Win2003 R2).  it doesn't happen on my staging server (32bit Win2003 R2).  I really do need to get this working but I have no idea where the problem is.

In addition to this issue, on my login form is a HTMLbox.  In IE the content of the htmlbox isn't drawing.  I get a 404 error.  in FF it draws about 1/2 the time.  the other 1/2 it is just blank.  The code in ithe box is GetSatisfaction code:

         <div>
                <script type="text/javascript" charset="utf-8">
                        var is_ssl = ("https:" == document.location.protocol);
                        var asset_host = is_ssl ? "https://s3.amazonaws.com/getsatisfaction.com/" : "http://s3.amazonaws.com/getsatisfaction.com/";
                        document.write(unescape("%3Cscript src='" + asset_host + "javascripts/feedback-v2.js' type='text/javascript'%3E%3C/script%3E"));
                    </script>

                <script type="text/javascript" charset="utf-8">
                        var feedback_widget_options = {};

                        feedback_widget_options.display = "inline";
                        feedback_widget_options.company = "dynacal";


                        feedback_widget_options.style = "question";

                        feedback_widget_options.tag = "OnlineSupport";



                        feedback_widget_options.limit = "10";


                        var feedback_widget = new GSFN.feedback_widget(feedback_widget_options);
                    </script>
            </div>

 

 

I only throw this problem in there in case it might help shed light on the big problem outlined here.

Thanks for any help you can give me.

Shawn

Re: why does my browser Window goes white 

I finally figured out what was causing this.  It is reproducible.

In IIS6’s IIS Manager go to the application pool that is servicing the VWG website.  In the properties go to the performance tab.  At the bottom is a setting for “Web Garden”  If this is not set to 1 then the problem will happen.  If this is changed to 1 then the problem does not happen.

 I was able to make the problem come and go by changing this setting.

 I am assuming this effects the session or context.  Is this correct?   

If I have this set to 1 will it cause me problems if there is a long running processes?

 Thanks,

Shawn
