Before i forget,
if you have in the dir of the server the test.html file with the following content:
<HTML>
<BODY>
<!--<div id="hiddenDiv" style="display:none;visible:hidden;">-->
<div id="hiddenDiv" style="display:none;visible:hidden;">
<iframe src="hidden.html" height="1" width="1" border="0" scrolling="no" name="hiddenFrame" id="hiddenFrame" ></iframe >
</div>
<img src="something.mjpeg" alt="Panda3dview" height="480" width="640">
<form target="hiddenFrame" method='POST' enctype='multipart/form-data'>
<!-- Set Quality: <input type=Value name=upfile> <input type=submit value=Set> -->
<div align="center">
Set Box Height:
<select name="upfile" width="50">
<option value="2"> 2 </option>
<option value="5"> 5 </option>
<option value="10"> 10 </option>
<option value="20"> 20 </option>
<option value="30"> 30 </option>
<option value="50"> 50 </option>
<option value="75"> 75 </option>
<option value="80"> 80 </option>
<option value="90"> 90 </option>
<option value="96"> 96 </option>
</select>
<input type=submit value=Set>
</div>
</form>
</BODY>
</HTML>If you open in the browser localhost:8080/test.html you get an interface to adjust the height of the rotating cube from the client. This could be cool for your next remote visualisation and controll project.
