2.8Procedure Invocation upon Request🔗 i

(require web-server/dispatchers/dispatch-pathprocedure )

package: web-server-lib

The web-server/dispatchers/dispatch-pathprocedure module defines a dispatcher constructor for invoking a particular procedure when a request is given to a particular URL path.

procedure
( make pathproc)→dispatcher/c
path:string?
proc:(request? . -> .response? )

Checks if the request URL path as a string is equal to path and if so, calls proc for a response.

This is used in the standard Web Server pipeline to provide a URL that refreshes the password file, servlet cache, etc.
