* Create separate `Retry-After` files for proxies Bad proxies are able to send a false `Retry-After` header and affect the availability of feeds (domain-wide) for other users. This PR starts including the address of the proxy if present in filenames for `Retry-After` to mitigate the issue. * Reduce code changes * Sync SimplePie fork https://github.com/FreshRSS/simplepie/pull/62 --------- Co-authored-by: Alexandre Alapetite <alexandre@alapetite.fr>
