Web Server CleanUp Question

This may sound like the dumbest question...but I'm NEW to Web Developement and ASP.net.

I've recently begun creating PDF using iTextSharp and if I write to the server and then use Window.Open to display it after the user does what ever they want with it (save, print, etc.) how do I get rid of it on the server so these files don't keep building up?

I tried to display the PDF using Window.Open and then delete the file on page unload but it appears that it deletes it before displaying it, so how do I know when the user is done with the file so I can remove it from the server?

OR

If I create the file using Response.Write...how can I open the file automatically instead of displaying the dialog box that gives the user the option to Open, Save or Cancel?  I wouldn't mind using Response.Write if I could automatically open the file on completion.

Thanks,
Mark

You can do one thing, once your user request for a file, before generating the file you should loop through the directory (where you save your file) and delete all files using IO namespace. So after that you generate one file which will be deleted on subsequent request from the users. That will make sure you will have only one file at a time on server.

Or if you want directly transfer file to response it can be done (assuming the user has Adobe Reader or any other PDF reader plugin installed on browser) by adding special lines to headers:
