Some characters are not allowed in paths always causes a stacktrace about prologue HOT 4 CLOSED

This also means that anyone can create a stack trace on a prologue server by requesting any URL with a forbidden character, regardless of if the server have a route with this forbidden character on. This does not seem to be a good design I believe.

from prologue.

See similar issue in #163

Reference: https://www.ietf.org/rfc/rfc2396.txt

The path may consist of a sequence of path segments separated by a single slash "/" character. Within a path segment, the characters "/", ";", "=", and "?" are reserved. Each path segment may include a sequence of parameters, indicated by the semicolon ";" character. The parameters are not significant to the parsing of relative references.

That means that in the path part of the URL (before the ? indicating the query string and after the host part) all characters are allowed except / (path delimiters), ; (path segment parameter), = (within the parameter ???) and ? (start of the query string). Path segment parameters is so rarely used I believe we can skip this. This means that any character can appear except ? (and % reserved for escapes of course).

from prologue.

I agree, it shouldn't check whether the requested path is a valid URL =>

from prologue.

After #183 is merged, you can use regex route like below

import prologue

proc hello*(ctx: Context) {.async.} =
  resp "<h1>Hello, Prologue!</h1>"

let app = newApp()
app.get("/", hello)
app.addRoute(re"/@group", hello)
app.run()

from prologue.
