We have an application where we export to Excel files using “UltraWebGridExcelExporter”, but it shows the following error:
"Internet Explore cannot download form.aspx of
"Unable to open this Internet website. The site you requested is not available or not found."
The website is installed in a security environment with SSL:
The parameter of the web server in the HTTP header is:
Cache-control = no-cache
Cache-control = no- store.
This is a problem with Internet Explorer and I cannot find a solution. Does anyone know how I can solve it?
Hello caod ,
Thank you for posting in our forums.
This issue is not related to Infragistics components.
It happens when you attempt to open or download a Microsoft Office document from a secure Web site in Internet Explorer.
It occurs because of the "Cache-control = no-cache" in the HTTP headers
Please refer to the below articles for more information.
