Network.Wai.Middleware.Static

Serve static files out of the application root (current directory). If file is found, it is streamed to the client and no further middleware is run. Disables caching.

Note: for security reasons, this uses the noDots and isNotAbsolute policy by default.

Serve static files subject to a Policy. Disables caching.

Note: for security reasons, this uses the noDots and isNotAbsolute policy by default.

Serve static files subject to a Policy. Unlike static and staticPolicy, this has no policies enabled by default and is hence insecure. Disables caching.

Serve static files out of the application root (current directory). If file is found, it is streamed to the client and no further middleware is run. Allows a CachingStrategy.

Note: for security reasons, this uses the noDots and isNotAbsolute policy by default.

Serve static files subject to a Policy using a specified CachingStrategy

Note: for security reasons, this uses the noDots and isNotAbsolute policy by default.

Serve static files subject to a Policy. Unlike static and staticPolicy, this has no policies enabled by default, and is hence insecure. Also allows to set a CachingStrategy.

Serve static files out of the application root (current directory). If file is found, it is streamed to the client and no further middleware is run. Takes Options.

Note: for security reasons, this uses the noDots and isNotAbsolute policy by default.

Serve static files subject to a Policy using specified Options

Note: for security reasons, this uses the noDots and isNotAbsolute policy by default.

Serve static files subject to a Policy. Unlike staticWithOptions and staticPolicyWithOptions, this has no policies enabled by default and is hence insecure. Takes Options.

Options for staticWithOptions Middleware.

Options can be set using record syntax on defaultOptions with the fields below.

Cache container to use

Compute MimeType from file name

Default options.

Options
{ cacheContainer = CacheContainerEmpty -- no caching
, mimeTypes      = getMimeType         -- use defaultMimeLookup from Network.Mime
}

A cache strategy which should be used to serve content matching a policy. Meta information is cached for a maxium of 100 seconds before being recomputed.

Meta information about a file to calculate cache headers

Initialize caching. This should only be done once per application launch.

Container caching file meta information. Create using initCaching

Take an incoming URI and optionally modify or filter it. The result will be treated as a filepath.

Choose between two policies. If the first fails, run the second.

Sequence two policies. They are run from left to right. (Note: this is mappend)

Lift a function into a Policy

Lift a predicate into a Policy

Add a base path to the URI

staticPolicy (addBase "/home/user/files")

GET "foo/bar" looks for "/home/user/files/foo/bar"

Add an initial slash to to the URI, if not already present.

staticPolicy addSlash

GET "foo/bar" looks for "/foo/bar"

Accept only URIs containing given string

Accept only URIs with given prefix

Accept only URIs with given suffix

Reject URIs containing ".."

Reject URIs that are absolute paths

Use URI as the key to an association list, rejecting those not found. The policy result is the matching value.

staticPolicy (only [("foo/bar", "/home/user/files/bar")])

GET "foo/bar" looks for "/home/user/files/bar" GET "baz/bar" doesn't match anything

Run a policy

Guess MIME type from file extension
