Re: [OSM-dev] Tiles cache and HTTPS

2019-11-04 Thread Yves
Hmm, if I anonymise x-forwarded-for, mod_tile will throttle the proxy, I'm 
afraid. 
Curious to know the config of the OSM CDN squid caches for https. Anybody for a 
short explanation?

In that case you would ideally find a way for the caching proxy server to
reach the original tiles over plain http (make sure to strip any user's
personal data from the requests!) and save some CPU cycles on both ends,
improving the latency slightly.

You might also want to consider serving larger tiles. 256x256 is really
small for today's standards and most major map frameworks (well, at least
leaflet, openlayers and mapbox) already support loading 512x512 tiles,
reducing the number of requests, improving the load times and server disk
usage. Yes, those tiles will take some more time to render, but most likely
less than four times more ;-)

Some rendering/caching systems internally already use even larger tiles to
combat these problems

Ah, I should've told that I own the opensnowmap render server.
My concern is to keep the ~0.5 TB of tiles available on both a proxy cache and 
the render server in case things goes bad on the later, even if only old tiles. 
Also, as heavy tiles user are more and more common, I'd like to propose them a 
quick solution that looks better than 'no warranty, I may have to cut your 
access'.

Re: [OSM-dev] Tiles cache and HTTPS

2019-11-02 Thread Stefan Baebler
Https might not be strictly needed between tile renderxcxer and the cache,
but if this is the only way that you can get to the tiles (eg from the
pucxcxccxczxcxzcxxxblic opensnowmap tile server) you can technically still
use that.

If possible try to use http 2 or at least keep-alive connections.

Also check their tile usage policy.
