URL dispatcher config Constructors Action HttpAction Simple answer, not depending on URL OneOf URLConf URLConf Try to dispatch URL with first URLConf, if error then try second Function StrAction Answer depends on last URL part (basename) Prefix String URLConf URLConf is executed only when URL starts with given prefix Regexp String URLConf URLConf is executed only when current part of URL matches regexp RegexpFun String StrAction Same, but answer depends on URL part ManyRegexpFun URLParts URLParts ManyStrAction Answer depends on many URL parts (which should match regexps) | After URLConf URLConf -- ^ Execute first URLConf, then second.

(-\>) :: String -> StrAction -> URLConf

If current part of URL matches given string, then run function

(~>) :: String -> StrAction -> URLConf

Same as RegexpFun

(~/) :: String -> URLConf -> URLConf

Forms ManyRegexpFun

(~>>) :: String -> ManyStrAction -> URLConf

Ends form ManyRegexpFun
