I am setting Content-disposition to Inline and filename = test-sql.txt and sending the file to be displayed automatically in IE. IE displays the file properly. If i set the filename = test1-attachment.txt. It opens an infromation bar. I dont know why this open for this file name only. I am using Windows XP with SP2 and IE 6.0. Is this problem because of filename, if so i need to know what is the reason for it.
