    <p>Instead of setting Content-Length in the request property, use setFixedLengthStreamingMode(postData.length);</p> <p>According to the source for <a href="http://www.docjar.com/html/api/sun/net/www/protocol/http/HttpURLConnection.java.html" rel="noreferrer" title="HttpURLConnection">HttpUrlConnection</a> , Content-Length is a "restricted header":</p> <pre><code>146 /* 147 * Restrict setting of request headers through the public api 148 * consistent with JavaScript XMLHttpRequest2 with a few 149 * exceptions. Disallowed headers are silently ignored for 150 * backwards compatibility reasons rather than throwing a 151 * SecurityException. For example, some applets set the 152 * Host header since old JREs did not implement HTTP 1.1. 153 * Additionally, any header starting with Sec- is 154 * disallowed. 155 * 156 * The following headers are allowed for historical reasons: 157 * 158 * Accept-Charset, Accept-Encoding, Cookie, Cookie2, Date, 159 * Referer, TE, User-Agent, headers beginning with Proxy-. 160 * 161 * The following headers are allowed in a limited form: 162 * 163 * Connection: close 164 * 165 * See http://www.w3.org/TR/XMLHttpRequest2. 166 */ 167 private static final boolean allowRestrictedHeaders; 168 private static final Set&lt;String&gt; restrictedHeaderSet; 169 private static final String[] restrictedHeaders = { 170 /* Restricted by XMLHttpRequest2 */ 171 //"Accept-Charset", 172 //"Accept-Encoding", 173 "Access-Control-Request-Headers", 174 "Access-Control-Request-Method", 175 "Connection", /* close is allowed */ 176 "Content-Length", 177 //"Cookie", 178 //"Cookie2", 179 "Content-Transfer-Encoding", 180 //"Date", 181 //"Expect", 182 "Host", 183 "Keep-Alive", 184 "Origin", 185 // "Referer", 186 // "TE", 187 "Trailer", 188 "Transfer-Encoding", 189 "Upgrade", 190 //"User-Agent", 191 "Via" 192 }; </code></pre> <p>So, setting Content-Length will be silently ignored.</p> <p>Authorization is blocked from being returned for security purposes:</p> <pre><code>249 // the following http request headers should NOT have their values 250 // returned for security reasons. 251 private static final String[] EXCLUDE_HEADERS = { 252 "Proxy-Authorization", 253 "Authorization" 254 }; 255 256 // also exclude system cookies when any might be set 257 private static final String[] EXCLUDE_HEADERS2= { 258 "Proxy-Authorization", 259 "Authorization", 260 "Cookie", 261 "Cookie2" 262 }; </code></pre> <p>So even if you set the authorization header, you won't get it back when you query the headers.</p>

    1. COi replaced the content length line with conn.setFixedLengthStreamingMode(postdata.length); still the output is The Request Properties: {Content-Type=[application/x-www-form-urlencoded;charset=UTF-8]} the authorization was never entered in the request properties :/, note that i also tried not setting the length at all

    3. COThe HttpURLConnection is doesn't allow you to set content length, and won't report it back to you. Authorization is specifically excluded from being returned in the properties map. I've updated and expanded my original answer to include a few more comments.

Querying!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
