We need to enable at least the following modules: headers, env, proxy, proxy_http, proxy_balancer. If we are proxying over AJP of course we should also enable proxy_ajp.

The following is a sample configuration for a site acting as a balancer to 2 instances of a backend application:

domain=cskh.mobi
#create jks
keytool -genkey -alias ${domain}.alias -keyalg RSA -deststoretype pkcs12 \
-storepass changeit -keysize 2048 -keystore ${domain}.jks \
-dname "CN=${domain}, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=US"

#view alias
keytool -v -list -keystore ${domain}.jks -storepass changeit | grep "Alias name\|Valid from:"

#export p12 base on domainalias

Download the certificate bundle. (https://curl.haxx.se/docs/caextract.html)

Put it somewhere. In my case, that was c:\wamp\ directory (if you are using Wamp 64 bit then it's c:\wamp64\).

Enable mod_ssl in Apache and php_openssl.dll in php.ini (uncomment them by removing ; at the beginning). But be careful, my problem was that I had two php.ini files and I need to do this in both of them. One is the one you get from your WAMP taskbar icon, and another one is, in my case, in C:\wamp\bin\php\php5.5.12\

Add these lines to your cert in both php.ini files:

#Edit the obfuscate file:
1. Find the line: "$___();$__________($______($__($_))); $________=$____();"
2. Delete all to end of file
3. Add some lines to see the original source code:
--------------------------------------
$source = base64_decode(gzuncompress(base64_decode($_)));
$idx = strpos($source, "eval(\$___)");
$orgSource = substr($source, $idx + 24);
echo "<br/>ORIGIN SOURCE<br/><pre> $orgSource </pre> <br/>";
