Holly ****.
Of course A URL is correct.
Guys, you spell
"A [you-r-l]" (U=you)
"A Uniform Resource Locator", because you spell [you-niform]
Even the whole word would need an "a", it does not matter:
UFO - Unidentified flying object.
If you write the whole name, then you need the "an".
This is "an Unidentified flying object", because the U is a spoken vowel.
If you use the short version, you must not use the "an".
This is "a UFO", because you spell [you-fo].
Never care about the whole version of a word, only care if the letter (right after the a/an) is a spoken vowel.
I hope this was understandable...
