my apologies. I should've compiled a minimal example with which to reproduce
the effect I see before jumping to conclusions. If I had, then I would've
realized that it is not the curl_easy_reset which leads to the effect I'm
seeing but https is.

Here a code snippet:

--%<---------------------------------------------------------------------------
#include <stdio.h>
#include <curl/curl.h>
#include <stdlib.h>

int main(void)
{
    CURL *curl;
    CURLcode res;

    curl = curl_easy_init();
    //curl_easy_setopt(curl, CURLOPT_PROXY, getenv("http_proxy"));
    curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
    curl_easy_setopt(curl, CURLOPT_URL, "https://www.mediafire.com/api/user/get_session_token.php");
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "foo=bar");

    res = curl_easy_perform(curl);
    if(res != CURLE_OK)
        fprintf(stderr, "curl_easy_perform() failed: %s\n",
                curl_easy_strerror(res));

    curl_easy_cleanup(curl);
    curl_global_cleanup();
    return 0;
}
-->%---------------------------------------------------------------------------

Compile and run it:

        $ gcc -lcurl http-post.c && http_proxy=127.0.0.1:8080 ./a.out

Assuming that the http proxy 127.0.0.1 does NOT exist, this should throw an
error, should it not? But it doesn't and performs the request anyways.

Now remove the comment from the CURLOPT_PROXY line above and run it again. This
time it will fail with "Failed to connect to 127.0.0.1 port 8080: Connection
refused" as expected.

So why for https requests do I have to explicitly set CURLOPT_PROXY?

This might now just as well be something in the documentation I missed.

Thanks!

cheers, josch

** [bugs:#1461] curl_easy_reset removes proxy information via environment**

Hi,
the documentation for curl_easy_reset says:
"Re-initializes all options previously set on a specified CURL handle to the default values. This puts back the handle to the same state as it was in when it was just created with curl_easy_init."
Suppose I have set the http_proxy environment variable. Then that one will be properly respected after a curl_easy_init. But once I do curl_easy_reset that information is lost.
So either above documentation has to be adapted to say "This puts back the handle to the same state as it was in when it was just created with curl_easy_init except that any proxy server set with the http_proxy environment variable is lost".
Or curl_easy_reset should respect the value of the http_proxy environment variable if it is set.
