### Functions

create | `open static fun create(): StaticHandler` Create a handler using defaults `open static fun create(root: String): StaticHandler` Create a handler, specifying web-root `open static fun create(root: String, classLoader: ClassLoader): StaticHandler` Create a handler, specifying web-root and a classloader used to load the resources.
setAllowRootFileSystemAccess | `abstract fun setAllowRootFileSystemAccess(allowRootFileSystemAccess: Boolean): StaticHandler` Enable/Disable access to the root of the filesystem
setAlwaysAsyncFS | `abstract fun setAlwaysAsyncFS(alwaysAsyncFS: Boolean): StaticHandler` Set whether async filesystem access should always be used
setCacheEntryTimeout | `abstract fun setCacheEntryTimeout(timeout: Long): StaticHandler` Set the server cache entry timeout when caching is enabled
setCachingEnabled | `abstract fun setCachingEnabled(enabled: Boolean): StaticHandler` Set whether cache header handling is enabled
setDefaultContentEncoding | `abstract fun setDefaultContentEncoding(contentEncoding: String): StaticHandler` Set the default content encoding for text related files. This allows overriding the system settings default value.
setDirectoryListing | `abstract fun setDirectoryListing(directoryListing: Boolean): StaticHandler` Set whether directory listing is enabled
setDirectoryTemplate | `abstract fun setDirectoryTemplate(directoryTemplate: String): StaticHandler` Set the directory template to be used when directory listing
setEnableFSTuning | `abstract fun setEnableFSTuning(enableFSTuning: Boolean): StaticHandler` Set whether async/sync filesystem tuning should enabled
setEnableRangeSupport | `abstract fun setEnableRangeSupport(enableRangeSupport: Boolean): StaticHandler` Set whether range requests (resumable downloads; media streaming) should be enabled.
setFilesReadOnly | `abstract fun setFilesReadOnly(readOnly: Boolean): StaticHandler` Set whether files are read-only and will never change
setIncludeHidden | `abstract fun setIncludeHidden(includeHidden: Boolean): StaticHandler` Set whether hidden files should be served
setIndexPage | `abstract fun setIndexPage(indexPage: String): StaticHandler` Set the index page
setMaxAgeSeconds | `abstract fun setMaxAgeSeconds(maxAgeSeconds: Long): StaticHandler` Set value for max age in caching headers
setMaxAvgServeTimeNs | `abstract fun setMaxAvgServeTimeNs(maxAvgServeTimeNanoSeconds: Long): StaticHandler` Set the max serve time in ns, above which serves are considered slow
setMaxCacheSize | `abstract fun setMaxCacheSize(maxCacheSize: Int): StaticHandler` Set the max cache size, when caching is enabled
setSendVaryHeader | `abstract fun setSendVaryHeader(varyHeader: Boolean): StaticHandler` Set whether vary header should be sent with response.
setWebRoot | `abstract fun setWebRoot(webRoot: String): StaticHandler` Set the web root
