Dear Daniel, I was in hurry when I sent my last mail. Here are the missing information.
I am doing this test on Ubuntu 9.10 on X86 machine with curl 7.20.1 and openssl 1.0.0. Can we use the curl_mutli with SSL options? Is this supported or SSL curl needs to be used only with the curl_easy ( I suppose this should not be ).

Here is he code snippet..... Open() { ..... curl_easy_setopt(file->handle.curl, CURLOPT_URL, url); curl_easy_setopt(file->handle.curl, CURLOPT_WRITEDATA, file); curl_easy_setopt(file->handle.curl, CURLOPT_VERBOSE, 1L); curl_easy_setopt(file->handle.curl, CURLOPT_WRITEFUNCTION, write_callback); curl_easy_setopt(file->handle.curl,CURLOPT_SSLCERTTYPE,"PEM"); curl_easy_setopt(file->handle.curl,CURLOPT_SSLCERT,"Path to Cert"); curl_easy_setopt(file->handle.curl,CURLOPT_SSLKEYTYPE,"PEM"); curl_easy_setopt(file->handle.curl,CURLOPT_SSLKEY," Path to Cert "); if(!multi_handle) multi_handle = curl_multi_init(); curl_multi_add_handle(multi_handle, file->handle.curl); do { res = curl_multi_perform(multi_handle, &file->still_running); }while(res == CURLM_CALL_MULTI_PERFORM ); } read( ) { ..... curl_multi_fdset(multi_handle, &fdread, &fdwrite, &fdexcep, &maxfd); rc = select(maxfd+1, &fdread, &fdwrite, &fdexcep, &timeout); switch(rc) { case -1: /* select error */ break; case 0: break; default: /* timeout or readable/writable sockets */ /* note we *could* be more efficient and not wait for * CURLM_CALL_MULTI_PERFORM to clear here and check it on re-entry * but that gets messy */ while(curl_multi_perform(multi_handle, &file->still_running) == CURLM_CALL_MULTI_PERFORM); break; } } while(file->still_running && (file->buffer_pos < want)); } Following output is seen..... * About to connect() to proxy 92.120.XX.XX port 3128 (#0) * Trying 92.120.XX.XX... * Establish HTTP proxy tunnel to "some sever here" * Proxy auth using Basic with user 'XXXXXXXX' > CONNECT some sever here HTTP/1.1 Host: some server here Proxy-Authorization: Basic VFJJRC1FVVxyYmlsYW1rYToxMndlbGNvbWU/ Proxy-Connection: Keep-Alive < HTTP/1.0 200 Connection established < * Proxy replied OK to CONNECT request * successfully set certificate verify locations: * CAfile: /etc/ssl/certs/ca-certificates.crt CApath: none * Expire cleared * SSL connection using RC4-MD5 After this, I don't see any action from CURL. The next print that I expect is ( as seen with curl_easy ) * Server certificate: * subject: XXXXXXXXXXXXX * start date: 2009-11-25 00:00:00 GMT * expire date: 2011-12-07 23:59:59 GMT * common name: XXXXX * issuer: XXXX * SSL certificate verify ok. Please let me know why curl_multi + SSL is not working.
