Sooris gave the correct answer here four years ago. Since then it has been confirmed by: BobK, Avalon, Vijajyjakhar, Tei, John007, sunnyrauf, quantumphyser. Beccky Jo Linton, Ronbee, okht-muslima, be real, arakolay, eslkorea, Clark, Tdol, marif0915, xpert. Nightmare85, isedehi and Amal-30.

I believe that it's "a" because we read URL like abbreviation of "Uniform Resource Locator" like /ju:ˌɑ:rˌəl/ here we've to say like a URL, but if we read it like one word like /ʌrl/, here we have to read it like an url. the rule of a, an is according to sounds not letters.
when using 'a,' the word that follows usually starts with a consonant, and it's singular.
A mountain. A piece of cake.
There is a glass of water.
The cat drank from a bowl of milk
When using 'an' the word that follows usually begins with a vowel or begins with a vowel sound, and it's singular.
