how to secure a file from unauthorized access

Hi,

I have created a page to upload pdf files to a file system. As an admin, I am suppose to be the only one accessing those files by clicking on any link to show the file. This is one of the files that I can access. myDomainName.mySite.com/Uploads/1809_UL.pdf

BUT, if someone else knows the URL address, he/she can access to all my files. The Question, how can I secure accessing the files and ONLY allow specific authenticated users to access the files.

Know the answer? Post it — somebody with the same question will find it here.

It is the same account you read, post and publish with — and you will come straight back to this page.

Hi,

You can use HTTP handlers. Please have a look on below article. (If your site is using ASP.NET)

I will also suggest you to please mention the technology (eg PHP, ASP.NET etc.) which you have used to create that page.

Hope this will help you.

Look into following URL, In that using C# .NET they will check roles and as per validation that particular user can able to access the file.
