The link validation feature of In-Link will automatically validate URLs of all created links. The validation is done by making a HTTP GET request to validated URL and checking response code. This works fine, when validating URLs to pages.

Using GET request can however result in a memory leaks, when validated URLs lead to large downloadable files, because file is downloaded completely and only then response HTTP code is checked.

Solution

  1. Make HEAD request instead of GET request. Specify "CURLOPT_NOBODY" option to "kCurlHelper" class before making the HTTP request in the "LinkValidationEventHandler::_validateLink" method.
  2. When HEAD request fails (some websites block HEAD requests) do a GET request.
