為了維持幾乎零延遲，裝置上決策活動包含以地理為基礎的對象，Adobe建議您在呼叫中提供地理值， getOffers. 若要這麼做，請設定 Geo 中的物件 Context 請求的。這表示您的伺服器需要一種方式來確定每個一般使用者的位置。例如，您的伺服器可能會使用您設定的服務，執行IP對地理位置的查詢。有些託管提供者(例如Google Cloud)會透過每個中的自訂標題提供此功能 HttpServletRequest.

不過，如果您無法在伺服器上執行IP對地理位置的查詢，但您仍想要執行裝置上決策的 getOffers 如果請求包含以地理為基礎的對象，這也受到支援。此方法的缺點在於它將使用遠端IP對地理的查詢，這會為每個查詢增加延遲 getOffers 呼叫。此延遲應低於遠端 getOffers 呼叫，因為它點選了位在伺服器附近的CDN。您必須僅提供 ipAddress 中的欄位 Geo 中的物件 Context ，以便SDK擷取您使用者IP位址的地理位置。如果除了任何其他欄位 ipAddress 「」提供的 Target SDK不會擷取地理位置中繼資料以進行解析。
