Hi all,

        I write a program using libcurl HTTPPOST method. It run sucessfully in RHEL_4, but the same program has different problems when it run in Redhat 9(shrike)&Fedora 7. All the libcurl version is 7.16.4. May be the problem is libcurl version is not right for Redhat 9 & Fedora 7. I have try to find the right version, but cann't get that one.
