# Hinter einem Proxy { #behind-a-proxy }

In vielen Situationen würden Sie einen **Proxy** wie Traefik oder Nginx vor Ihrer FastAPI-App verwenden.

Diese Proxys könnten HTTPS-Zertifikate und andere Dinge handhaben.

## Proxy-<abbr title="weitergeleitete Header">Forwarded-Header</abbr> { #proxy-forwarded-headers }

 *  New: We've added `requestFailed()` and `responseFailed()` methods to `EventListener`. These
    are called instead of `requestBodyEnd()` and `responseBodyEnd()` in some failure situations.
    They may also be fired in cases where no event was published previously. In this release we did
    an internal rewrite of our event code to fix problems where events were lost or unbalanced.

    when a request body needs to cancel its own call.


## Version 4.2.1

_2019-10-02_

 *  Fix: In 4.1.0 we introduced a performance regression that prevented connections from being
    pooled in certain situations. We have good test coverage for connection pooling but we missed
    this because it only occurs if you have proxy configured and you share a connection pool among
    multiple `OkHttpClient` instances.

 * conventional bounded queues, which either block or reject new elements when full.
 *
 * <p>This implementation is based on the <a
 * href="http://portal.acm.org/citation.cfm?id=6621">min-max heap</a> developed by Atkinson, et al.
 * Unlike many other double-ended priority queues, it stores elements in a single array, as compact
 * as the traditional heap data structure used in {@link PriorityQueue}.

    logs.

 *  **WebSocket API now uses `RequestBody` and `ResponseBody` for messages.**
    This is a backwards-incompatible API change.

 *  **The DNS service is now pluggable.** In some situations this may be useful
    to manually prioritize specific IP addresses.

 *  Fix: Don't throw when converting an `HttpUrl` to a `java.net.URI`.
    Previously URLs with special characters like `|` and `[` would break when

Au final, dans les deux situations, il est fort probable que **FastAPI** soit tout de même [plus rapide](index.md#performance){.internal-link target=_blank} que (ou au moins de vitesse égale à) votre framework précédent.

		} else {

// unescapeGeneric is similar to url.PathUnescape or url.QueryUnescape
// depending on input, additionally also handles situations such as
// `//` are normalized as `/`, also removes any `/` prefix before
// returning.
func unescapeGeneric(p string, escapeFn func(string) (string, error)) (string, error) {
	ep, err := escapeFn(p)
	if err != nil {

Still, in both situations, chances are that **FastAPI** will [still be faster](index.md#performance){.internal-link target=_blank} than (or at least comparable to) your previous framework.
