Tim Posted February 9, 2015 Share Posted February 9, 2015 Hi, In my project i have been using UniSession.CallbackUrl to obtain a target URL for file uploads. After deploying the project as an ISAPI DLL, i realised that this is a little problematic, because URLs returned by UniSession.CallbackUrl don't include the DLL name. So i switched to UniSession.CallbackUrlEx, which has an option to return an absolute URL. However, the form's OnAjaxEvent, which i am using to process the uploaded files, doesn't get triggered if i use a URL returned by UniSession.CallbackUrlEx. So i compared the URLs and noticed that URLs returned by UniSession.CallbackUrlEx include the following additional parameter: __EXCB__=1 When i remove this parameter, the form's OnAjaxEvent *does* get triggered when a file is uploaded. So this way seems to work -- i'm just wondering if this is a safe approach? What is the purpose of the __EXCB__ parameter? Many thanks, Tim Quote Link to comment Share on other sites More sharing options...
Administrators Farshad Mohajeri Posted February 9, 2015 Administrators Share Posted February 9, 2015 __EXCB__=1 This parameter says that uniGUI should execute this as callback not as an Ajax event. I will resolve the ISAPI issue in next build. Quote Link to comment Share on other sites More sharing options...

Tim Posted February 12, 2015 Author Share Posted February 12, 2015 Thanks for the fix in v0.99.0.1148. I have tested UniSession.CallbackUrl under ISAPI in my project and it works fine 1 Quote Link to comment Share on other sites More sharing options...
