Guild Wars 2

I just fumbled on the same problem on my project, i was considering posting but you made it before i do

Thank you for the post, and Healix, for the answer !

You mean that a change in the image is somewhat detectable in the HTTP header ?

The modification I was speaking of were in Kessex. And as you can see on the following image, they are put on the map :
!https://tiles.guildwars2.com/1/1/7/41/57.jpg!

Sweet work you’ve done !

The difference is that my app is local (but that is not the subject )
In the app i handle the tiles individually, so that’s not a problem.

Hello everybody
As this is my first post here, I wanted to thanks everybody for their works and questions and explanations that allowed me to not drown in the API and their usage.

So my question is :
I created a little map program : Minimap
It works in windowed mode for the moment.

This use a cache method for the map, because my goal is to make a tool with low bandwidth usage, and quick at display.

The problem is, when an update is made in the map of gw2, how can I know which tiles must be re-downloaded ?
I thought about deleting them at each change of version, but it’s not the best way since all the tiles will have to be downloaded again.

Is there a way I didn’t see ? or if not, is it possible to have in the future some information about the tile version (a new API ?) ?

Thanks you in advance
