GRANBLUE FANTASY CACHING PROXY

Why use this software

• Because your browser cache just isn't enough for how much multimedia-rich content you view.
• Because you think that your latency to Akamai's CDN is too high and want to locally cache Granblue Fantasy assets. (The latency is a factor when your browser checks the asset server for modifications before using the cached version.)

Modern browsers will cache a ton of data, but what if it's not enough to cache your regular browsing data and Granblue Fantasy assets? I have no idea if this actually is an issue, but I wrote this caching proxy anyway.

How to use this software

0. Don't use this software.
1. Modify gbf-proxy.ini if you want.
2. Setup environment and run:

    pip install -r requirements.txt
    python gbf-proxy.py

4. Point your browser to the proxy configuration in gbf-proxy.ini (default: localhost:8080).

Tips

You can use PAC files so that you don't need to proxy ALL your browser traffic through mproxy-gbf. Here is a sample PAC file:

function FindProxyForURL(url, host) {
	if (shExpMatch(url, "*.granbluefantasy.jp/*")) {
		return "PROXY localhost:8080";
	}

	return "DIRECT";
}

Chrome on Windows with PAC files

Chrome uses Windows' proxy settings, so you have to tell Windows to use your PAC file.

Firefox with PAC Files

I think you can tell Firefox to use a PAC file.

Assets aren't loading or something is missing

Currently, there isn't anything implemented to verify cache data. So things could go wrong. For example, music may never load due to a hiccup when the music is first cached.

In the worst case, you can nuke the entire cache directory and start fresh.
