In the previous section, you learned how to use the GeoServer tile cache. In this section, you'll learn about resolving issues that may arise with tile caching. First, you'll learn how to resolve the most common source of tile caching errors: parameters. Next, you'll learn about issues arising from rendering tiles. Finally, we'll review some other issues that may occur. The following example is showing a particular URL that includes parameters running through curl, which you saw in the previous section:
