Forward CURL request on the Fly

Question

I need to forward CURL requests on the fly that is written in php. a php program send request to: XYZ.COM

is there any way to forward its request to another location ?

can i use .htaccess ?

please let me know if there is any solution.

php script is encoded & we dont have access to its source code. script is web based.

Answer 1

What you are trying to do is forward request based on User-Agent . Since that header can be set freely, there is no way you can 100% assure that you are getting all request coming from a curl client.

Imagine this cURL command execution

curl --user-agent "freetext" http://www.example.com

If you are sending the request yourself you could do

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, "http://www.example.com");
curl_setopt($ch, CURLOPT_USERAGENT, "myagent");
// ...
// all the other parameters needed 
// taken from http://www.php.net/manual/de/book.curl.php

the Apache RewriteRule would look like this

RewriteCond %{HTTP_USER_AGENT}  ^myagent$
RewriteRule ^(.*)$ https://www.example.com/curl/$1  [L,302]
