WHAT IS MIME SNIFFING? The web browser "sniffs" the content to analyze what file format that particular asset is. Once the browser has completed its analysis, it compares what it found against what the web server provided in the Content-Type header (if anything). If there is a mismatch, the browser uses the MIME type that it determined to be associated with the asset. HOW TO REDUCE JPEG FILE SIZE In the world of digital image storage, JPEG is one of the most common ways to encode information. While it may be most familiar to you in the form of a .jpeg or .jpg file extension (read more about the difference between JPG and JPEG), JPEG is actually a means of compressing, or reducing, the size of an image..

HOW ANYCAST WORKS

What is anycast? Anycast, also known as IP anycast, is a networking technique that allows for multiple machines to share the same IP address.
