Two different errors in excel save method

Hi!
I’ve encountered with some problems using Aspose.Excel.
When i trying to save my xls-file, sometimes i get one of these errors:
1. Exception message=‘Errors in Excel Save method:0’
Inner exception message='Server cannot append header after HTTP headers have been sent.'
2. Exception message=‘Errors in Excel Save method:0’
Inner exception='The remote host closed the connection. The error code is 0x80072746.'
What is strange for me is that i have these errors not permanently but from time to time.

Thanks.

Hi,

We think it's caused by IIS setting.

Please check your web server setting and install the latest patch of MS.
