Regex

[alangueu]

hello members, I am a new regex student and it is very challenging to me I have a very important question to ask about regex.
I am actively looking for an answer about this please help me
Thanks


Please verify that the following regex will correctly test that the input data is a well-formed HTTP request.

"(?i)\\A(\\x20|\\t)*(([A-Z]|[A-Z]-?|[A-Z]_?){2,19}[A-Z])(\\x20|\\t)++.+(\\x20|\\t)++HTTP\\x2F1\\x2E(0|1)(\\x20|\\t)*"

What are its limitations?
