manage big file in laravel.(how to load?)

I've a proxy file, it has 5000 different proxies, currently what I'm doing is, loading all proxies using Configurations(Laravel Config I personally thought that it is not a good technique). So please suggest some solution about this issue, another possible solution is to put file in storage directory and access it. I'm looking for some solution with good reason. Thanks

PS: I need one random proxy in each request(throughout the application life cycle), So what best way could be to implement it?

Thanks again.
