Securing PDF Files
-
Recently i came here to discuss the issue, how to secure files (pdf), the recomendation was httphandelers, it works absolutely great.But now an new issue has been arrived. What i did , i registerd ISAPI extension (.pdf) in IIS 6.0,to let process the request to ASP.Net runtime, there i used context.response.transmitfile to send the file to the browser, as client will be viewing file in browser not downloading, but in case when file is bigger than 20 MB ,(file can be upto 100MB), it takes time, obviously it should take. But when we redirect or request pdf file without registering ISAPI extension, browser starts showing file, means you see instantly first page or few pages while other are downloading, how to achive this kind of performance, and this kind of behaviour, with letting asp.net runtime process the request. I hope you guys get my question & if any explaination needed please ask. Note: Same issue with uploading files with .Net uploader control, even after we change machine.config file size attribute, i want suggestion about better performance, when many users are doing both uploading, and viewing files from repository.
