File download doesn't work with SSL

Everyone, I've had a simple download script working where a user would click on a link and the program would send word or excel headers instead of HTML. The file would then be opened in the appropriate program and the user could save/edit it. Now that we've loaded everything under SSL, it doesn't work. Here are the headers I send: header("content-type: application/vnd.ms-excel; name='excel'"); header("content-disposition: attachment; filename=" . $filename . ".xls"); Now, the pages in question are just regular HTML tables. If there is a export2=excel in the URL, then these two additional headers will be sent. The dialog to save/open the file pops up, but when you try to open/save the file, IE says it cannot be found. If I put in a echo before these two headers (or comment them out), the page is shown correctly as HTML, so the code is correct. Are there any special headers I have to send to enable this file download while under SSL, or is it something else I'm overlooking? Thanks for any help. ---John Holmes...
