What are RFC’s?
The term comes from the days of ARPANET, the predecessor to the internet, where the researchers would basically just throw ideas out there to, well, make a request for comments from the other researchers on the project.

That way of counting also makes the maximum length vary with the number of labels, so when you have four labels the maximum length is … Read more
Why is form enctype=multipart/form-data required when uploading a file?
It has to do with how the browser packages binary and form data for transmission over HTTP. By default only form data is sent, but if the form needs to support uploading a file, then the binary data must also be appended and separated from the form data. Scott Hanselman gives a good explanation of … Read more
