I downloaded and compiled curl on cygwin, version 3.1.5-1 using: ./configure --disable-shared --enable-debug --prefix=/usr
The build completed correctly. When I attempt to use curl to access an https:// REST endpoint that takes up to 5 minutes to respond with the: --keepalive-time 5 command line option, and I watch the TCP traffic via wireshark, I do not see any TCP Keep-Alive packets. Without the keep-alive packets the request fails. curl/libcurl version curl 7.71.0-DEV (x86_64-pc-cygwin) libcurl/7.71.0-DEV OpenSSL/1.1.1f zlib/1.2.11 Release-Date: [unreleased] operating system CYGWIN_NT-10.0 IT008 3.1.4(0.340/5/3) 2020-02-19 08:49 x86_64 Cygwin Running the win32 version of curl does work as expected, and I see the Keep-Alive packets being sent every 5 seconds, and the REST call does complete correctly. The official curl build does not work any better, that's why I tried to download and rebuild the code. Does anyone know why the --keepalive-time option is not working with cygwin? -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
