BlackBerry browser caching even with no-cache meta tags -


okay so, firstly website user sees list of tasks uncomplete. should work user clicks complete button , item no longer shows, seems not though!

when click 'complete' item have onclick function executes sql update statement , response.redirect page, sql statement executes correctly, page redirect list item still there!

if user exits page , comes list item has disappeared, makes me think page caching, have put following in place stop this:

<meta http-equiv="cache-control" content="no-cache, must-revalidate, post-check=0, pre-check=0" />
<meta http-equiv="pragma" content="no-cache" />
<meta http-equiv="expires" content="-1" />

which fine on blackberry bold running os 5.0, not work customers blackberry bold running os 4.x

any ideas of appreciated.

try this:

<!doctype html public "-//w3c//dtd html 4.01 transitional//en"> <html>   <head>     <meta http-equiv="expires" content="0">     <meta http-equiv="pragma" content="no-cache">     <title>expires example page</title>   </head>   <body>     hello world!   </body> </html>
