 70 | 				<h2>About</h2>
 71 | 				<p>CORS proxy is a free service for developers who need to bypass <a href="https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy">same-origin policy</a> related to performing standard <a href="https://developer.mozilla.org/en-US/docs/AJAX/Getting_Started">AJAX requests</a> to 3rd party services.</p>
 72 | 				<p>You can simply use this website as quickest way to finally start doing some cross-domain requests and even you can run this service on your own webserver. If you prefer running the service on your own, follow the instructions in <a href="#how-to-setup">Setup</a> section.</p>
 73 | 				<p>You can customize the service parameters to fit your own needs (including this front-end page template).</p>
 74 | 			</section>
 75 | 			<hr>
 76 | 			<section id="how-to-use">
 77 | 				<h2>How to use</h2>
 78 | 				<p>The CORS proxy service expects you provide the URL of 3rd party service/page in <code>url</code> HTTP GET parameter by default. A final cross-domain request URL via the CORS proxy service can be handled, looks something like this:</p>
 79 | 				<pre><?php echo $domainUrl; ?><?php echo $basePath; ?>/?<?php echo $config->getUrlParameterName(); ?>=https://www.htmldriven.com/sample.json</pre>
 80 | 
 81 | 				<h3>Try the CORS proxy now</h3>
 82 | 				<p>You can test the CORS proxy service response using the form above.</p>
 83 | 			</section>
 84 | 			<hr>
 85 | 			<section id="setup">
 86 | 				<h2>Setup</h2>
 87 | 				<p>Read the following section if you want to run the CORS proxy on your own webserver.</p>
 88 | 
 89 | 				<h3>Requirements</h3>
 90 | 				<p>Please, check the <a href="https://www.github.com/htmldriven/cors-proxy/blob/master/composer.json">composer.json</a> file or <a href="https://packagist.org/packages/htmldriven/cors-proxy">packagist.org</a> to see the current list of requirements in terms of packages which are required by <a href="https://getcomposer.org">composer</a>. Except for PHP version >=5.6 with CURL extension being installed, there are no more odd requirements</p>
 91 | 
 92 | 				<h3>Installation</h3>
 93 | 				<p>The best way to install the CORS proxy is using the <a href="https://getcomposer.org">composer</a>. You can do that using the following command:</p>
 94 | 				<pre>composer create-project htmldriven/cors-proxy my-cors-proxy</pre>
 95 | 				<p class="">* Note that my-cors-proxy in the command above is the name of target directory for newly created CORS proxy project, so this name is totally up to you.</p>
 96 | 				<p>Then, create a destination database using the <a href="https://www.github.com/htmldriven/cors-proxy/blob/master/app/database/cors-proxy.sql">cors-proxy.sql</a> initialization script.</p>
 97 | 
 98 | 				<h3>Configuration</h3>
 99 | 				<p>If you need, you can customize the CORS proxy by creating custom config.ini file. This file must be located at app/config directory. There's already config.sample.ini file, which you can just copy and edit some parts of it to match your needs.</p>
100 | 				<p>There are several config items which you can change. The following list shows all supported options:</p>
101 | 				<ul>
102 | 					<li><code>urlParameterName = url</code> - name of URL HTTP GET parameter name</li>
103 | 					<li><code>userAgent = htmldriven/cors-proxy 1.0</code> - HTTP User-Agent string which is used during cross-domain requests</li>
104 | 					<li><code>templateFile = app/templates/default/frontend.phtml</code> - path to main front-end page template file</li>
105 | 					<li><code>sitemapPath = /sitemap.xml</code> - URL path to sitemap file</li>
106 | 					<li><code>sitemapFile = app/templates/default/sitemap.pxml</code> - path to sitemap XML template file</li>
107 | 					<li><code>timezone = UTC</code> - default PHP timezone settings used for DateTime instances</li>
108 | 					<li><code>database = ...</code> - database connection settings</li>
109 | 				</ul>
