Hi, See my following testings:
werner@X10DAi-01:~/Desktop$ curl -sv --head http://mirrors.ctan.org/systems/texlive/Images/texlive2020-20200406.iso |& grep ^Location: Location: http://mirrors.tuna.tsinghua.edu.cn/CTAN/systems/texlive/Images/texlive2020-20200406.iso werner@X10DAi-01:~/Desktop$ curl -sv --head http://mirrors.ctan.org/systems/texlive/Images/texlive2020-20200406.iso |& grep ^Location: Location: http://mirrors.hit.edu.cn/CTAN/systems/texlive/Images/texlive2020-20200406.iso werner@X10DAi-01:~/Desktop$ curl -sv --head http://mirrors.ctan.org/systems/texlive/Images/texlive2020-20200406.iso |& grep ^Location: Location: http://mirrors.nju.edu.cn/CTAN/systems/texlive/Images/texlive2020-20200406.iso As you can see, it seems libcurl returns the random URL for the target file. I want to know whether libcurl has the capability of obtaining all the potential mirror's URLs. -- Hongyi Zhao <hongyi.z...@gmail.com> ------------------------------------------------------------------- Unsubscribe: https://cool.haxx.se/list/listinfo/curl-library Etiquette: https://curl.haxx.se/mail/etiquette.html
