Strange Issue with using ExportToHttpResponse for exporting to Excel

Question

Hi,
We are working with BO XI R2 with .Net 2.0.
We are using ExportToHttpResponse method to export the Crystal Report to pdf/excel and directly opening the export in a browser window.
Code being used is as follows :
For pdf :  rd.ExportToHttpResponse(ExportFormatType.PortableDocFormat, oResponse, false, Name);
For Excel : rd.ExportToHttpResponse(ExportFormatType.Excel, oResponse, false, Name);
where 'rd' is ReportDocument instance.
The strange issue here is that for pdf output this works as desired and the exported report is directly opened in the browser window. However when it comes to Excel ; it does not open the exported file in the browser window and gives a prompt to open/save file. Even if the 'asAttachment' parameter of ExportToHttpResponse method is set to false it still is sending the exported file as an attachment to the browser and not opening it directly (as it is happening in the case of a pdf export )
Do we need to set the Response.ContentType to excel ; if yes then why it is working in case of pdf.
Can any one please advise about this strange issue .
Thanks

Thanks for the response Ludek .
I was going through some othere threads and saw that ExportToHttpResponse is more preferred over ExportToStream . I even checked for setting up the Response.ContentType to Excel . I think I shoulfd give it a try to use ExportToStream.
Let me know if any one else has any other suggestion(s).
