System is win2k, IIS5.0<BR><BR>I have a page which loads an excel file:<BR><BR>&#060;%<BR>response.contenttype = "application/"<BR>Response.AddHeader "content-disposition", "filename=icl.xls"<BR>Server.Transfer("docs/icl.xls")<BR>%&#062;<BR><BR>I get highly inconsistant behavior depending on how I attempt to access this file:<BR><BR>If I call its URL directly, half the time it loads the excel file, the other half, it loads the excel interface and puts the ASP code in it. (It does this on a rotating basis, 1 correct load, followed by 1 incorrect load)<BR><BR>If I call this file through a LINK or a form using the POST method, a Save File or Open File from location window appears. No matter which option I choose, about 90% of the time, the excel contents are the ASP page.<BR><BR>If I call the file through a form using the GET method, it works 100% of the time, no popup, no problem.<BR><BR>Any idea what is going on here?
