Multiple KMLs and 414 Error: Request-URI Too Large

Question

I've got plenty of KML files - one for each of the existing countries. I need to render them dynamically on Google Map based on user's input. If I there are only a few countries as result of searching, everything works perfectly - the map displays all the countries. The problem occurs when there are more than about 15 countries do highlight. I get 414 errors for almost all KML requests.

As far as I know, Google Map is divided on tiles and for each of the tiles, one KML request is proceeded. If there's too many KML files that need generated for a tile, then URL for such a request is too long (414 error).

Do you have any idea how can I overcome this problem?

Here is an example of such a request:

您是否必须将它们保存在单独的kml文件中，是否可以只输出带有多个文件夹的xml，并且每个文件夹内的每个区域都是一个想法，请让我知道它是否是垃圾
