Php 多个KML和414错误：请求URI太大

我有很多KML文件，每个国家都有一个。我需要根据用户的输入在谷歌地图上动态渲染它们。如果我发现搜索结果中只有几个国家，那么一切都很完美——地图显示了所有国家。当大约有15个以上的国家确实存在时，问题就出现了。几乎所有KML请求都会出现414个错误

据我所知，GoogleMap是分块的，对于每个分块，一个KML请求被处理。如果需要为磁贴生成太多的KML文件，则此类请求的URL太长（414错误）

你知道我怎样才能克服这个问题吗

以下是此类请求的一个示例：

谢谢你的帮助

你必须把它们放在单独的kml文件中吗？你能用多个文件夹输出你的xml吗？每个文件夹中都有每个区域只是一个想法如果是垃圾请告诉我
