OK it works, thanks again for your help Daniel, I indeed didn't clean
the curl buffer before performing a page fetch. At the beginning of my
perform function, I added the following code:

    if (mem->memory)
    {
        free(mem->memory);
    }
    mem->size = 0;
    mem->memory = NULL;

It works perfectly now !

7.11.1 is pretty old. Consider updating.

That's not what libcurl does. It is your code that appends the contents
of
page 2 to to the contents of page 1.

Based on your snippet, it looks like a modified getinmemory.c example
where
you don't reset things in between the requests.

Every time you set CURLOPT_URL, it clears the previous setting and
stores the
new one you provide. Setting it multiple times before you call
curl_easy_perform() would only be stupid.

No.
