Allows me to redirect some websites to others that I like more (for whatever reason).

Unfortunatelly userscripts does not achieve the exact same behavior. The redirection when using it is slightly slower.

An alternative is redirect-web which is amazing but I think it's easier to add the rules by code than by an interface.

Therefore I decided to write an iOS Safari Extension. This may serve as inspiration for others.

All the relevant code is inside content.js. The redirection is done entirely with javascript.
