The http-equiv="refresh" attribute sets the page to auto-refresh. The page will be
requested at the rate (in seconds) set in the value of the content attribute. In the
example above, the page will be requested approximately every 5 seconds. If
you set the value for the page refresh too short, the page may not have enough
time to be displayed before it is requested.

You do not have to refresh the whole page and different parts of the display can
update at different rates. This feature is achieved by using the tag, <br>inline frames. If you insert <IFRAME> tags in cells in a table, each cell in the <br>table can update at a specific rate. This is accomplished by placing the <meta <br>http-equiv="refresh" content="5"> command in the <HEAD> section of each file <br>referenced by each <IFRAME> tag. Example code (contained in 3 separate files) <br>to perform this task is given below: </p><p style="position:absolute;top:407px;left:140px;white-space:nowrap" class="ft02"> </p><p style="position:absolute;top:440px;left:84px;white-space:nowrap" class="ft03"><b>5.9 File_1.htm </b></p><p style="position:absolute;top:475px;left:140px;white-space:nowrap" class="ft01"><html> </p><p style="position:absolute;top:492px;left:140px;white-space:nowrap" class="ft01"><head> </p><p style="position:absolute;top:509px;left:140px;white-space:nowrap" class="ft01"><meta http-equiv="refresh" content="2"> </p><p style="position:absolute;top:526px;left:140px;white-space:nowrap" class="ft01"><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </p><p style="position:absolute;top:544px;left:140px;white-space:nowrap" class="ft01"><meta name="IFRAME TEST" content="Microsoft FrontPage 3.0"> </p><p style="position:absolute;top:561px;left:140px;white-space:nowrap" class="ft01"><title>Point 0 (2 Sec)</title> </p><p style="position:absolute;top:578px;left:140px;white-space:nowrap" class="ft01"></head> </p><p style="position:absolute;top:595px;left:140px;white-space:nowrap" class="ft01"><Body><--DATA 0,1,1,%d --></Body> </p><p style="position:absolute;top:612px;left:140px;white-space:nowrap" class="ft01"></html> </p><p style="position:absolute;top:628px;left:140px;white-space:nowrap" class="ft02"> </p><p style="position:absolute;top:661px;left:84px;white-space:nowrap" class="ft03"><b>5.10 File_2.htm </b></p><p style="position:absolute;top:696px;left:140px;white-space:nowrap" class="ft01"><html> </p><p style="position:absolute;top:713px;left:140px;white-space:nowrap" class="ft01"><head> </p><p style="position:absolute;top:731px;left:140px;white-space:nowrap" class="ft01"><meta http-equiv="refresh" content="5"> </p><p style="position:absolute;top:748px;left:140px;white-space:nowrap" class="ft01"><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </p><p style="position:absolute;top:765px;left:140px;white-space:nowrap" class="ft01"><meta name="IFRAME TEST" content="Microsoft FrontPage 3.0"> </p><p style="position:absolute;top:782px;left:140px;white-space:nowrap" class="ft01"><title>Point 1 (5 Sec)</title> </p><p style="position:absolute;top:799px;left:140px;white-space:nowrap" class="ft01"></head> </p><p style="position:absolute;top:816px;left:140px;white-space:nowrap" class="ft01"><Body><--DATA 1,1,1,%d --></Body> </p><p style="position:absolute;top:833px;left:140px;white-space:nowrap" class="ft01"></html> </p><p style="position:absolute;top:849px;left:140px;white-space:nowrap" class="ft02"> </p><p style="position:absolute;top:883px;left:84px;white-space:nowrap" class="ft03"><b>5.11 Index.htm </b></p><p style="position:absolute;top:917px;left:140px;white-space:nowrap" class="ft01">…Normal header stuff </p><p style="position:absolute;top:935px;left:140px;white-space:nowrap" class="ft01"><Body> </p><p style="position:absolute;top:952px;left:140px;white-space:nowrap" class="ft01"><table border="0" width="100%"> </p><p style="position:absolute;top:969px;left:140px;white-space:nowrap" class="ft01"> <tr> </p><p style="position:absolute;top:986px;left:140px;white-space:nowrap" class="ft01"> <td width="10%"> </p><p style="position:absolute;top:1003px;left:140px;white-space:nowrap" class="ft01"> <IFRAME src=”File_1.htm” name=”iframe1” frameborder=1 scrolling=no </p><p style="position:absolute;top:1020px;left:140px;white-space:nowrap" class="ft01">align=middle> </p><p style="position:absolute;top:1038px;left:140px;white-space:nowrap" class="ft01">
