How many slashes are after file:// protocol for www and UnityWebRequest?

It was different for different Unity version, I need to know the current status on Unity 2017.2.0

Windows Desktop: file://C:/... (2 slashes, it was 3 slashes before Unity 2017)

iOS: file:///var/... (2 slashes, because persistantdatapath returns with 1 slash. However, it doesn't work in Unity 2017.2.0, www returned 404.)

Android: file:///storage/....(2 slashes, because persistantdatapath returns with 1 slash. no issue.)

Windows Phone: file://C:/... (2 slashes)

Are these correct? How to solve iOS file issue? should it be file://var or file:///var?

 

There are always two slashes in file://, just like there are always two slashes in http:// and ftp://. Whatever is after that depends on the path. All Unix-based operating systems use "/" for the root (so, everything except Windows basically). The only way file://var would work is if there's a folder called var in the current path, which is unlikely since presumably you're trying to get the var folder in root, which is /var.

You missed my point. I typed "..." at every location(I forgot the last two.). iOS persistant data path returns with /var at the beginning, so I type var.

and after some test, I find out that iOS should be file:///var/... . two slash plus persistant data path.

Now I have another question: There was an issue long time ago, that on iOS, load a string from url using www will be unconditionally cached. And when I change the content inside the url, www will not load the newest string, but the old cached one, even when I call a method that disable www cache. I have to add a parameter after the url like ?p=20171017123015468, so that iOS think that this is a new url. Is this bug already fixed?

 

I didn't miss your point at all...I know that /var isn't the complete path; it wasn't relevant. If you read what I said, it answered your question.
