[Mapbender-users] Connection = CURL - Frage zu Einstellungen

[Ingo Lünsmann]

Dies hört sich nach einem ähnlichen Problem, was ich vor ca. 1,5 Jahren
hatte. Damals habe ich die getHTTP()-Methode in class_connector.php
gepatcht, so dass ich in die mapbender.conf Proxy-Ausnahmen eintragen kann.
Vielleicht hilft es ja weiter. Hier die gepatchte class_connector.php (im
Verzeichnis mapbender/http/classes):

----
Und die beispielhaften Eintraege in der mapbender.conf:

define("CONNECTION_PROXY", "proxy_server_ip");
define("CONNECTION_PORT", "3128");
define("CONNECTION_USER", "");
define("CONNECTION_PASSWORD", "");
define("NON_PROXY_HOSTS","localhost|janeway");

Bitte achte auf Groß- und Kleinschreibung...
