# Server Actions
# Server Actions in ASP.NET MVC PDF Viewer

Syncfusion<sup style="font-size:70%">&reg;</sup> PDF Viewer is a client-server control that processes PDF documents on the server and sends incremental responses to the client for rendering and interaction. Ensure the ASP.NET MVC controller routes are registered, dependency injection supplies `IHostingEnvironment` and `IMemoryCache`, and caching is configured to persist page data between requests. Validate file paths and restrict inputs to trusted locations to avoid exposing sensitive files.
