This change renames directories in preparation for the great package rename. The repository is now in a broken state because the code itself hasn't been updated. However this should ensure that git correctly preserves history for each file.

/**
|
||||
* Human-Friendly HTTP WHOIS API
|
||||
*
|
||||
* <p>This API uses easy to understand paths rather than {@link WhoisServer} which
|
||||
* requires a POST request containing a WHOIS command. Because the typical WHOIS command is
|
||||
* along the lines of {@code "domain google.lol"} or the equivalent {@code "google.lol}, this
|
||||
* servlet is just going to replace the slashes with spaces and let {@link WhoisReader}
|
||||
* figure out what to do.
|
||||
*
|
||||
* <p>This servlet accepts requests from any origin.
|
||||
*
|
||||
* <p>You can send AJAX requests to our WHOIS API from your <em>very own</em> website using the
|
||||
* following embed code:
|
||||
*
|
||||
* <pre>
|
||||
* <p>
|
||||
* <input id="query-input" placeholder="Domain, Nameserver, IP, etc." autofocus>
|
||||
* <button id="search-button">Lookup</button>
|
||||
* <p>
|
||||
* <pre id="whois-results"></pre>
|
||||
* <script>
|
||||
* (function() {
|
||||
* var WHOIS_API_URL = 'https://domain-registry-alpha.appspot.com/whois/';
|
||||
* function OnKeyPressQueryInput(ev) {
|
||||
* if (typeof ev == 'undefined' && window.event) {
|
||||
* ev = window.event;
|
||||
* }
|
||||
* if (ev.keyCode == 13) {
|
||||
* document.getElementById('search-button').click();
|
||||
* }
|
||||
* }
|
||||
* function OnClickSearchButton() {
|
||||
* var query = document.getElementById('query-input').value;
|
||||
* var req = new XMLHttpRequest();
|
||||
* req.onreadystatechange = function() {
|
||||
* if (req.readyState == 4) {
|
||||
* var results = document.getElementById('whois-results');
|
||||
* results.textContent = req.responseText;
|
||||
* }
|
||||
* };
|
||||
* req.open('GET', WHOIS_API_URL + escape(query), true);
|
||||
* req.send();
|
||||
* }
|
||||
* document.getElementById('search-button').onclick = OnClickSearchButton;
|
||||
* document.getElementById('query-input').onkeypress = OnKeyPressQueryInput;
|
