The outcome of request can be some more HTTP requests and it is acceptable.

I am trying to generate a sphere based on 3D walk plot and was almost successful.

I am working on a server project where I need to collect data from the user in the form of .dat file and I have to process it and display the result online. The problem I am facing is once the user uploads the file there is no issue. But, assume user clicks on add files button, he selects multiple files and before clicking on upload button if he or she feels that one or some files in the selected list has to be removed, it cannot be done. Is this a known limitation? Is it browser dependant? Are there any solutions for the above said issue? Thank you for you time.
