I'm trying to use a forward proxy server (Apache Traffic Server or Squid) on my local machine, as a local HTTP cache for my cURL calls.
I've set up the proxy using:
curl_setopt($ch, CURLOPT_PROXY, 'http://localhost:8080');
When I query an HTTP website, cURL performs a standard HTTP GET proxy request, which can be cached properly:
GET http://example.com/ HTTP/1.1
However, when querying an HTTPs website, cURL performs a CONNECT instead, effectively using the proxy as a TCP tunnel, and preventing it from caching the response:
CONNECT example.com:80 HTTP/1.1
Is there a way to force cURL to perform a GET request even for HTTPs websites?
I can understand the rationale behind using a TCP tunnel for HTTPs requests over an HTTP proxy for security, but because my proxy server is on localhost, I don't care using an insecure HTTP connection to the proxy, and would like cURL to perform a GET request:
GET https://example.com/ HTTP/1.1
I tried using:
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, false);
But this didn't change anything.
