- Details

When reusing a libcurl handle for sequential transfers driven by environment-variable proxy configuration, libcurl fails to clear the proxy authentication state between requests. Specifically, if the initial transfer authenticates against
proxyAusing Digest auth, a subsequent transfer routed throughproxyBerroneously leaks theProxy-Authorization:header intended solely forproxyA. - References
