TFPHTTPClient avec interrogation d'un service WXS: OK sous Windows, ne fonctionne pas sous Linux

Bjr à tous,

Après reprise de mon extracteur d'altitude via un service IGN wxs, je constate que TFPHTTPClient fonctionne très bien avec une URL ordinaire. Par contre, dès que j'interroge le service wxs via les méthodes TFPHTTPClient.Get() ou TFPHTTPClient.Post(), le résultat de get() est une chaîne vide, alors que la même URL dans un navigateur me retourne du XML.
Sous Windows: OK , sous Linux: KO
