Firefox (Browser): 65536, actual test longest word length 4098 (may be server limit)

Safari (Browser)
The maximum URL length is limited to 80,000 characters.

Opera (Browser)
The maximum URL length is limited to 190,000 characters.

Google (Chrome)
Not found, the estimate is also gray long ~ ~ ~

In addition, the maximum number of characters per server limit is also different, that is, if the browser supports a lot of character URLs, submitted to the server, will still be intercepted.
