Descripción

*** Pendiente de traducción *** libcurl might in some circumstances reuse the wrong connection when asked to<br /> do Negotiate-authenticated ones, even when they are set to use different<br /> &amp;#39;services&amp;#39;.<br /> <br /> libcurl features a pool of recent connections so that subsequent requests can<br /> reuse an existing connection to avoid overhead.<br /> <br /> When reusing a connection a range of criteria must be met. Due to a logical<br /> error in the code, a request that was issued by an application could<br /> wrongfully reuse an existing connection to the same server that was<br /> authenticated using different services.
