Hi as this is an international list I will respond in English.
At least for OpenStreetMap I know the reason. They are blocking the requests. The real reason for this is unknown. I can just guess: OSM project requires the "User-Agent" to be set in the HTTP header for each request. They use that information to analyze the web traffic by applications. One goal is to detect leeching of tiles as this is expensive. It looks like the OSM project put a ban on the "User-Agent" string used by the *tms files. Why? Don't know. Either: * They simply blocked everything they do not consider as fitting "User-Agent" string to lower the load of their servers. And "Agent Smith" is not considered as proper string. ;) or: * Someone is miss-using that string to leech tiles. or: * Some users of QMapShack systematically load/view whole areas of tiles triggering some kind of leeching detection. Anyways if you enter another string it works again. And this is exactly the situation I feared, when OSM did introduce that "User-Agent" thing years ago. Still, I am not convinced that this is the appropriate thing to handle the abuse of the OSM servers. It's very simple to spoof. And blocking requests by that string might hit the real cause for a short time but it will cause collateral damage, too. And the bad guys simply change it to another string and go on with the abuse. It's ridiculous and just causing trouble for the well behaving users. But that's how the cooky crumbles. Don't get me wrong. I totally understand the point of OSM to limit bandwidth and cost of their servers to a fair usage. QMapShack does not provide any mechanism to automatically load a complete map area other than the current viewport. And it does cache the loaded tiles. Thus using QMapShack should be similar to using a browser. If there are other suggestions how to limit the load on the servers I am happy to help by changing the code. I just do not think that filtering on the "User-Agent" does keep the bad guys away. Oliver > Gesendet: Sonntag, 26.
