URL by podla RFC mali byt case insensitive, ak sa pouzije lowercase schema, cize ak uzivatel klikne na http://, tak mas spracovat case insensitive url.
https://www.ietf.org/rfc/rfc1738.txt
; the scheme is in lower case; interpreters should use case-ignore
scheme = 1*[ lowalpha | digit | "+" | "-" | "." ]
Ze stejného dokumentu:
In general, URLs are written as follows:
<scheme>:<scheme-specific-part>
A URL contains the name of the scheme being used (<scheme>) followed
by a colon and then a string (the <scheme-specific-part>) whose
interpretation depends on the scheme.
Scheme names consist of a sequence of characters. The lower case
letters "a"--"z", digits, and the characters plus ("+"), period
("."), and hyphen ("-") are allowed. For resiliency, programs
interpreting URLs should treat upper case letters as equivalent to
lower case in scheme names (e.g., allow "HTTP" as well as "http").
Takže se jedná o scheme část URL neboli jestli je URL http nebo HTTP nebo to je třeba HtTp ap. je jedno, ale nic to nevypovídá o case sensitivitě dalších částí jako je scheme-specific-part a path za tím.
