Correctly switching between HTTP and HTTPS using .htaccess

I use something similar to this for my admin folder in wordpress: #redirect all https traffic to http, unless it is pointed at /checkout RewriteCond %{HTTPS} on RewriteCond %{REQUEST_URI} !^/checkout/?.*$ RewriteRule ^(.*)$$1 [R=301,L] The RewriteCond %{HTTPS} on portion may not work for all web servers.

Programmatically reading a web page

Have a look at the cURL library: #include <stdio.h> #include <curl/curl.h> int main(void) { CURL *curl; CURLcode res; curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, “”); res = curl_easy_perform(curl); /* always cleanup */ curl_easy_cleanup(curl); } return 0; } BTW, if C++ is not strictly required.

Chunked encoding and content-length header
