S routingem v Go/Goa jsem zatim moc nepracoval, tam mozna strilim uplne vedle, ale nejak se mi nezda/nelibi to, ze musis ruco rekonstruovat cely request znovu. Predstavoval jsem si, ze se pouzije jednoduse neco jako httputil.ReverseProxy.

Zkusil jsem to loopnout s Claudem a pochopil jsem, ze tam je pak problem, ze je to mimo Goa a takze to neni pokryte v API docs. Osobne bych se tim nejak netrapil 🙂 nebo se to da "hacknout" stub endpointem. Zkus mrknout na tohle #2576, co by si na to rekl. Za me to ma jednu major vyhodu - proste to forwardne ten request, jak je - zadny cusotm handling body, headeru atp. (a to je to, co chceme - proste forwardnout request)
