读取文件而不在服务器上存储？

Question

I have created a program that decrypts whats stored in a export file from a certain program,

at the moment people need to open the file and copy and paste into a text feild, i know that i can use the form type "file" but to read the contents of what has been POSTED it needs to be saved to the server if i am correct?

Is there no way of just reading the file contents without saving it to the server?

Thanks!

Answer 1

POSTing to the server doesn't necessarily mean that it's saved on the server in anyway.

Though, if I'm reading your question correctly, a file POSTed to a server will be stored temporarily on the server.

Why do want/need to avoid this?
