Hello, I am a developer, my company just purchased the Page Blaster module, we have plans to roll out Page Blaster to our DNN production website very soon. However, during the compatibility testing of Page Blaster with our existing website, I observed that Page Blaster does not seems to play nice with AJAX style pages. From the logging within Page Blaster, each time Page Blaster hit a AJAX response page (JP.aspx in the following example) there is always the following exception: 5/12/2007 4:35:20 PM PB:PageController:GetCachedPage: Page not found in disk cache:

5/12/2007 4:35:20 PM PB:PageController:IsPageExcluded: Exception:
Message: Object reference not set to an instance of an object.
StackTrace: at Snapsis.HttpModules.PageBlaster.PageController.IsPageExcluded(HttpApplication app, ExcludeFrom excludeFrom, Settings settings)
The XML data returned from the AJAX response page is something like this.
[William St, Northbridge~~William St;Northbridge;�:6464797]~~POINT]]> > Dr;Morley;�:6471490]~~POINT]]> , Morley]]> ~POINT]]> [Myrtle Ct, Morley~~Myrtle Ct;Morley;�:6472765]~~POINT]]> > :6472958]~~POINT]]>
I understand that the data being return from an AJAX request is kind of adhoc, so it should not be cached anyway. However, I think because Page Blaster and AJAX style pages are not playing nicely right now, I did run into some unexpected results.
As an example, for the logged-in users my understand is that there should be no caching at all. So I was expecting all the AJAX pages to work nicely once a user has logged in. However, this is not the case, I believe the Object Reference not set exception, is stopping the pages that should be excluded from really being excluded.
Can anyone with more knowledge of Page Blaster please tell me what they believe is going on? Right now, I have a long list of AJAX style aspx pages added to the config file for exclusion. Thank you, Hadwin. |
