Caching Issues with Adobe Flex and HTTPservice

[Former Member]

I faced a strange issue a coupla days back. In one of my Applications I had a Timer which would fire every 10 secs and would fetch data using a HTTPService call when fired. Surprisingly though, the initial results fetched by the HTTPservice was cached and would not reflect any changes when the data changed in the background, in IE, however the problem would not occur in Firefox !

I sort of hacked the HTTPService url to add a random number at the end of the call to make it believe that it was calling a different URL every time and it worked. But I would definitely like to know the reason for this behavior

The solution for this case is to use POST method (if possible) where IE wont cache

Hi, Abesh.

I ran into the same thing, but it did not do this until recently! I had recently installed Flex 3.0 beta, so maybe something changed with the compiler and/or the Flash VM in this regard. Also, you can change the behavior of the Flex/Flash runtime by changing the caching settings in IE (check page for newer version on each visit).
