| | | 2 | | .SYNOPSIS |
| | | 3 | | Registers a static file server to serve files from a specified path. |
| | | 4 | | .DESCRIPTION |
| | | 5 | | This cmdlet allows you to serve static files from a specified path using the Kestrun server. |
| | | 6 | | It can be used to serve files like images, stylesheets, and scripts. |
| | | 7 | | .PARAMETER Options |
| | | 8 | | The StaticFileOptions to configure the static file service. |
| | | 9 | | .PARAMETER RootPath |
| | | 10 | | The root path from which to serve static files. |
| | | 11 | | .PARAMETER RequestPath |
| | | 12 | | The path at which the static file service will be registered. |
| | | 13 | | .PARAMETER HttpsCompression |
| | | 14 | | The HTTPS compression mode to use for the static files. |
| | | 15 | | .PARAMETER ServeUnknownFileTypes |
| | | 16 | | If specified, allows serving files with unknown MIME types. |
| | | 17 | | .PARAMETER DefaultContentType |
| | | 18 | | The default content type to use for files served by the static file service. |
| | | 19 | | .PARAMETER RedirectToAppendTrailingSlash |
| | | 20 | | If specified, redirects requests to append a trailing slash to the URL. |
| | | 21 | | .PARAMETER ContentTypeMap |
| | | 22 | | A hashtable mapping file extensions to MIME types. |
| | | 23 | | .PARAMETER NoCache |
| | | 24 | | If specified, adds a 'no-cache' directive to the Cache-Control header. |
| | | 25 | | .PARAMETER NoStore |
| | | 26 | | If specified, adds a 'no-store' directive to the Cache-Control header. |
| | | 27 | | .PARAMETER MaxAge |
| | | 28 | | If specified, sets the 'max-age' directive in seconds for the Cache-Control header. |
| | | 29 | | .PARAMETER SharedMaxAge |
| | | 30 | | If specified, sets the 's-maxage' directive in seconds for the Cache-Control header |
| | | 31 | | (used by shared caches). |
| | | 32 | | .PARAMETER MaxStale |
| | | 33 | | If specified, adds a 'max-stale' directive to the Cache-Control header. |
| | | 34 | | .PARAMETER MaxStaleLimit |
| | | 35 | | If specified, sets the limit in seconds for the 'max-stale' directive in the Cache-Control header. |
| | | 36 | | .PARAMETER MinFresh |
| | | 37 | | If specified, sets the 'min-fresh' directive in seconds for the Cache-Control header. |
| | | 38 | | .PARAMETER NoTransform |
| | | 39 | | If specified, adds a 'no-transform' directive to the Cache-Control header. |
| | | 40 | | .PARAMETER OnlyIfCached |
| | | 41 | | If specified, adds an 'only-if-cached' directive to the Cache-Control header. |
| | | 42 | | .PARAMETER Public |
| | | 43 | | If specified, adds a 'public' directive to the Cache-Control header. |
| | | 44 | | .PARAMETER Private |
| | | 45 | | If specified, adds a 'private' directive to the Cache-Control header. |
| | | 46 | | .PARAMETER MustRevalidate |
| | | 47 | | If specified, adds a 'must-revalidate' directive to the Cache-Control header. |
| | | 48 | | .PARAMETER ProxyRevalidate |
| | | 49 | | If specified, adds a 'proxy-revalidate' directive to the Cache-Control header. |
| | | 50 | | .EXAMPLE |
| | | 51 | | Add-KrStaticFilesMiddleware -RequestPath '/static' -HttpsCompression -ServeUnknownFileTypes -DefaultContentTyp |
| | | 52 | | This example adds a static file service to the server for the path '/static', enabling HTTPS compression, allowi |
| | | 53 | | setting the default content type to 'application/octet-stream', and redirecting requests to append a trailing sl |
| | | 54 | | .EXAMPLE |
| | | 55 | | Add-KrStaticFilesMiddleware -Options $options |
| | | 56 | | This example adds a static file service to the server using the specified StaticFileOptions. |
| | | 57 | | .EXAMPLE |
| | | 58 | | Add-KrStaticFilesMiddleware -RequestPath '/static' -MaxAge 600 -Public -MustRevalidate |
| | | 59 | | This example adds a static file service to the server for the path '/static', setting caching headers with a max |
| | | 60 | | marking the response as public, and adding the must-revalidate directive. |
