-Problems connecting to SSL servers.
+1. Problems connecting to SSL servers.
-===================================
 
   It took a very long time before I could sort out why curl had problems
   to connect to certain SSL servers when using SSLeay or OpenSSL v0.9+.

   I have also seen examples where the remote server didn't like the SSLv2
   request and instead you had to force curl to use SSLv3 with -3/--sslv3.
 
-Does curl support resume?
+2. curl: (1) SSL is disabled, https: not supported
-=========================
+
+  If you get this output when trying to get anything from a https:// server,
+  it means that the configure script couldn't find all libs and include files
+  it requires for SSL to work. If the configure script fails to find them,
+  curl is simply built without SSL support.
+
+  To get the https:// support into a curl that was previously built but that
+  reports that https:// is not supported, you should dig through the document
+  and logs and check out why the configure script doesn't find the SSL libs
+  and/or include files.
+
+  Also, check out the other paragraph in this FAQ labeled "configure doesn't
+  find OpenSSL even when it is installed".

+3. Does curl support resume?
 
   Yes. Both ways on FTP, download ways on HTTP.
 
-Is libcurl thread safe?
+4. Is libcurl thread safe?
-=======================
 
-  Yes, as far as curl's own code goes. It does use system calls that often
+  As version seven is slowly marching in as the libcurl version to use, we
-  aren't thread safe in most environments, such as gethostbyname().
+  have made a serious attempt to address all places in the code where we could
+  forsee problems for multi-threaded programs. If your system has them, curl
+  will attempt to use threadsafe functions instead of non-safe ones.
 
   I am very interested in once and for all getting some kind of report or
   README file from those who have used libcurl in a threaded environment,
   since I haven't and I get this question more and more frequently!

+  8.2. only the libssl lib is missing
+
+    If all include files and the libcrypto lib is present, with only the
+    libssl being missing according to configure, this is mostly likely because
+    a few functions are left out from the libssl.
+
+    If the function names missing include RSA or RSAREF you can be certain
+    that this is because libssl requires the RSA and RSASEF libs to build.
