There's a huge lack of details in your mail, but I would guess that your
request failed already on the CONNECT and you're not checking the
CURLINFO_HTTP_CONNECTCODE.

And your proxy server allows this? What response headers do you get back
from
your proxy?

Hello All,
I would like to compile cURL support with PHP 4.4.2. I take a recent
version of curl/libcurl (the latest) it compile well.
when i compil i have this message :
/src/php-4.4.2/ext/curl/curl.c: In function `zm_startup_curl':
/src/php-4.4.2/ext/curl/curl.c:207: `CURLOPT_FTPASCII' undeclared (first
use in this function)
/src/php-4.4.2/ext/curl/curl.c:207: (Each undeclared identifier is
reported only once
/src/php-4.4.2/ext/curl/curl.c:207: for each function it appears in.)
/src/php-4.4.2/ext/curl/curl.c:245: `CURLOPT_PASSWDFUNCTION' undeclared
(first use in this function)
All the CURL file on the harddrive have been deleted before installing new
libs. i try from RPM, rebuild RPM, of From Source. Same errors !
Also, i found a solution, but ...
for CURLOPT_FTPASCII :
in curl sources : lib/url.c
case CURLOPT_TRANSFERTEXT:
    /*
     * This option was previously named 'FTPASCII'. Renamed to work with
     * more protocols than merely FTP.
     *
     * Transfer using ASCII (instead of BINARY).
     */
    data->set.prefer_ascii = (bool)(0 != va_arg(param, long));
    break;
-> is CURLOPT_FTPASCII is renamed by CURLOPT_TRANSFERTEXT ?
-> is CURLOPT_PASSWDFUNCTION is misdeclared in lib (not present in .h file
?) that PHP don't find it well ? If i comment in curl.c the 2 lines
concerned, it's work well ...
Philippe,

Right, these symbols have been erased from libcurl now since they've been
obsolete and deprecated for many years. You should probably:
1 - use a more recent PHP that doesn't use these symbols
2 - modify the PHP/CURL source code to use the correct symbols and mail the
     PHP team a patch or possibly:
3 - if there is none, report it as a bug to the PHP team
4 - use an older libcurl release where they were still present
