Dave Fletcher at Daresbury, who is responsible for the UK
crystallographic database service, came up with a simple solution to
prevent jmol/java caching CIF drawings. <br><br>
First the problem:<br><br>
<blockquote type=cite class=cite cite="">If I draw a structure by loading
a file "local4.cif" as usual like:<br>
<pre>jmolApplet(600,'load "local4.cif" { 3 3 3 }; etc...
</pre>and then I change the contents of my file "local4.cif"
and redraw it, the drawing remains the same even though when I
"view" the file from the jmol window the new contents are
correctly listed</blockquote><br>
Now Dave's solution was simply to replace the call to jmolApplet
with...<br>
<blockquote type=cite class=cite cite=""><pre>jmolApplet(600,'load
"local4.cif?$id[0]" { 3 3 3 }; etc...
</pre></blockquote>where $id[0] is a number unique for each structure.
Surprisingly (?) jmol doesn't complain about this ?$id[0] appendix to the
file name. Dave explains it like this:<br><br>
<blockquote type=cite class=cite cite="">The ?$id[0] is different for
each structure, so stops the caching, but<br>
everything after the ? is part of the GET query string which is not used
by Jmol.</blockquote><br>
Thanks Dave. I was surprised and delighted that something so simple
worked. Alan.<br>
