About this question
Why should we sometimes use --+ instead of -- in SQL injection to comment the rest of the query? I have encountered some websites where when I used -- + to comment on the rest of the query it didn't work, but when I tried --+ it worked.
In the MySQL official documentation there is no such thing as --+ and we only have -- and two other ways.
Why does this happen? I want to know exactly why this works sometimes and -- doesn't, and why there is no --+ for comments in the MySQL man page?
