adding curl_setopt to class-http.php.. is it possible in wp-config?

Hi:

I’ve got a client to has a server where curl isn’t using RC4-SHA by default. They’ve been wanting a connection to a site which only uses https. Each time we try to connect via wp_remote_post() it fails. Checking curl on the command line I see

curl -v -S -k -3 https://sitewewanttoconnect.to

curl: (35) Cannot communicate securely with peer: no common encryption algorithm(s).

However… adding

curl -v -S -k -3 –cipher rsa_rc4_128_sha

works fine.

Digging around I found
wp-includes/class-http.php

search for $timeout = (int) ceil( $r[‘timeout’] );

and add after

curl_setopt( $handle, CURLOPT_SSL_CIPHER_LIST, ‘rsa_rc4_128_sha’ );

Once thats in there everything works great.

I would recompile curl IF I had root rights to…

So question… is there a way to do this via wp-config.php so future wordpress updates don’t step on this?

Thanks
