How to avoid loading aw.js at each page

is it possible to load aw.js and aw.css in an hidden frame and use then in all the other pages:which will avoid loading these files each time we need.

All browsers have strategy for cache, u dont need worry about this.

Infact, u need write the sript url in each page, iframe its not a good idea anymore :-)

Pc is right, usually browsers have caching enabled.

Just keep in mind that the Web server must also be properly configured in a way that it doesn't sends headers for invalidating cache (and so, making caching mechanisms useless on purpose). With this I mean HTTP headers like:

Pragma: no-cache
Cache-Control: no-cache

Regards,

ok but you don't answer my question.
I found the solution and now performance is much better

Would like to know your solution Thierry.

To pc from brazil, even if javascript is cached, does that mean the parse tree of the javascript is cached? Does that mean the construction of the classes is cached?

1/ dividing en frames like this (that is an exemple)
<frameset rows="96,*" frameborder="NO" border="0" framespacing="0" cols="*">

<frame name="xheader" scrolling="NO" noresize src="xheader.php" >

<frameset cols="163,*" frameborder="NO" border="0" framespacing="0" rows="*">

<frame name="xtoc" noresize src="xtoc.htm">

<frameset rows="*,1" frameborder="NO" border="0" framespacing="0" cols="*">

<frameset cols="15,*" frameborder="NO" border="0" framespacing="0">

<frame name="xtoc2" scrolling="NO" noresize src="xtoc2.htm">

      <frame name="xcontent" src="index.php?x=x">

     </frameset>;

     <frame name="xcontrole" scrolling="yes" noresize src="xcontrole.htm">

    </frameset>

  </frameset>

</frameset>

2/ Include in xheader frame the AW code in one <div>

<div id="toto">
<script>
here aw.js coding
</script>
</div>

3/ In each page

replace <script src="runtime/lib/aw.js"></script>

by this
<script>
document.write(parent.xheader.document.getElementById("toto").innerHTML);
</script>

I think that .js library is downloaded only one time.

If the cache is enabled, the browser will not download the js again, only if the lastModified has changed.

how about change the src attribute with runtime/lib/aw.js?timestamp=1171044604

will it be uncached?

yes, the client will always retrieve the new file. (if the timestamp value change every time).
