What is a HTTPS Post?
A HTTPS POST is a request method supported by the HTTPS protocol and is sent over SSL. By design, the POST request method requests that a web server accept the data enclosed in the body of the request message, most likely for storing it. It is often used when uploading a file or when submitting a completed web form. Here at dlptest.com we don’t store any info from the HTTPS Post but most websites will store your data.
