Progress bar not moving on production server (but works on dev box)

[Craig]

Here are the problem details. If anyone has any ideas, I would appreciate it:

1. Using ASP.NET AJAX Q2 2013 SP1
2. Simple file upload page using RadUpload,RadProgressManagerand RadProgressArea  (see aspx page and web.config below)
3. Progress bar moves and updates properly running on developer machine using IIS 7.5.
4. But, when running on Windows 2008 R2 server using IIS 7.5, the following happens:
   • Progress bar does not move
   • The Uploaded percentage and byte count remain at zero during the upload.
   • The progress area filename is blank during the upload.
   • The file DOES successfully upload.
   • When upload is complete, upload percentage is 100% and byte count matches total file size.
5. Used fiddler to compare dev machine vs server mid-progress traffic and noticed JSON progress status details are zero/blank when run on server. And they are correct when run on dev machine (see comparison below)

// Running on Server
var rawProgressData = {InProgress: true,
ProgressCounters: true,
CurrentOperationText: '',
PrimaryTotal: '168.26MB',
PrimaryValue: '0B',
PrimaryPercent: '0',
SecondaryValue: '0',
Speed: '0B/s',
TimeElapsed: '20311',
TimeEstimated: '2147483647',
OperationComplete: 'false',
RadUpload: { RequestSize: 176433547, Bytes: 0, FilesCount: 0, CurrentFileName: '', RequestLength: 176433547 }};

 

// Running on developer machine
var rawProgressData = {InProgress: true,
ProgressCounters: true,
CurrentOperationText: 'C:\\test\\test.zip',
PrimaryTotal: '168.26MB',
PrimaryValue: '102.49MB',
PrimaryPercent: '61',
SecondaryValue: '0',
Speed: '191.21MB/s',
TimeElapsed: '536',
TimeEstimated: '344',
OperationComplete: 'false',
RadUpload: { RequestSize: 176433596, Bytes: 107464352, FilesCount: 0, CurrentFileName: 'C:\\test\\test.zip',RequestLength: 176433596 }};

Hi Craig,

What is the name of the page? Is it Default.aspx, if so please try to open the page as you include it in the url:

http://localhost/Default.aspx and test again.

If this doesn't help, please send us a fiddler log.
