<?php /* Full-Text RSS config */ // ......IMPORTANT...................................... // ..................................................... // Please do not change this file (config.php) directly. // Save a copy as custom_config.php and make your // changes to that instead.

Similarly with frameworks/CMS which display // feed content - the content should be treated like any other user-submitted content. // // If you are writing an application yourself which is processing feeds generated by // Full-Text RSS, you can either filter the HTML yourself to remove potential XSS attacks // or enable this option. This might be useful if you are processing our generated // feeds with JavaScript on the client side - although there's client side xss // filtering available too, e.g. https://code.google.com/p/google-caja/wiki/JsHtmlSanitizer // // If enabled, we'll pass retrieved HTML content through htmLawed with // safe flag on and style attributes denied, see // http://www.bioinformatics.org/phplabware/internal_utilities/htmLawed/htmLawed_README.htm#s3.6 // Note: if enabled this will also remove certain elements you may want to preserve, such as iframes. // // Valid values: // true - enabled, all content will be filtered // 'user' (default) - user must pass &xss in makefulltextfeed.php querystring to enable // false - disabled $options->xss_filter = 'user'; // Allowed parsers // ---------------------- // Full-Text RSS attempts to use PHP's libxml extension to process HTML. // While fast, on some sites it may not always produce good results. // For these sites, you can specify an alternative HTML parser: // parser: html5lib // The html5lib parser is bundled with Full-Text RSS. // see http://code.google.com/p/html5lib/ // // To disable HTML parsing with html5lib, you can remove it from this list. // By default we allow both: libxml and html5lib. $options->allowed_parsers = array('libxml', 'html5lib'); //$options->allowed_parsers = array('libxml'); //disable html5lib - forcing libxml in all cases // Enable Cross-Origin Resource Sharing (CORS) // ---------------------- // If enabled we'll send the following HTTP header // Access-Control-Allow-Origin: * // see http://en.wikipedia.org/wiki/Cross-origin_resource_sharing $options->cors = false; // Use APC user cache? // ---------------------- // If enabled we will store site config files (when requested // for the first time) in APC's user cache.
