SpringClientFactory returns null if the class is not aware of IClientConfig.
This change catches the exception when trying the constructor with IClientConfig so classes that aren't aware of IClientConfig can be created.
Fixes gh-1608
Some webserver are picky with the encoding (uWSGI for example) and the current code behavior of decoding and reencoding the query string can lead to valid requests
rejected by the backend after the modifications in Zuul. This commit adds an optional parameter to force the original encoding of the query string in SimpleHostRoutingFilter.
Fixes gh-971
RxJavaReturnValueHandlerConfig can only be loaded when both spring-web
and spring-webmvc are on the classpath, because it contains a reference
to the WebMvcConfigurerAdapter class.
But the ConditionalOnClass annotation only included the class from
spring-web. In our situation, only spring-web was on the classpath,
resulting in a NoClassDefFoundError for WebMvcConfigurerAdapter. Fix it
by adding that class to the condition as well.
Instead of blocking them (which is the default behaviour of a
Spring MVC controller) Cors requests will flow through the Zuul
filters by default. Users can control it by grabbing the
ZuulHandlerMapping in a @PostConstruct and injecting some
CorsConfiguration via its setCorsConfigurations() method.
This fixes most of the issues people encounter when there are
multiple proxies in the request. The tricky thing is that there
is another header "Forwarded" that we don't recognize, but which
backends probably do, at least some of the time (since it is
from an actual RFC). The problem is that "Forwarded" does not
contain the ports, so Spring UriComponentsBuilder cannot use it
to rewrite links to a specific port. Since we do not support it
already, this change doesn't make things any worse, but the
corner case is there still.
Secure ribbon urls were forced to use https scheme via UriComponentsBuilder, that was created from original uri. This transformation url encoded previously encoded url parts that were used to create builder. This was introduced in c883495.
This change fixes double url encoding using RibbonUtils.updateToHttpsIfNeeded that fixes double escaping case and corner case with '+' in url as well.

Previously, parameter names with colons (ie foo:bar), caused an IllegalArgumentException because 41c364002f introduced UriTemplate to properly encode.
