Problem with Cache

[howdena]

Hi,

We're using the JavaScript dataURL method, and we're passing some parameters in the data URL, but it looks like FusionCharts is also adding another parameter called FCTime with a date/time value into the list of parameters.

We DO NOT want this extra parameter to be added - it is possible to prevent it?

Thanks,

Andy

Andy,

 

 

 

It's not possible to directly remove it. You can customize the source code to remove this, though.

I'd also like to modify the code to disable the appendage of the FCTime variable, but I'm not a Javascript guru, and I can't find the specific location in the .js file where the querystring is being added. Can you point me in the right direction for disabling this?

 

 

 

Thanks,

That code is not present in JS - but rather FusionCharts source code.

Is there any way to prevent the generation of that parameter in the request? It breaks the cache, removing any possibility of setting etag or cache control headers.

[Pallav]

You'll have to customize the code to attain that.

This is a major bug in my humble opinion. Especially since this "feature" cannot be disabled in JavaScript.

 

 

 

Please remove the code from the charts and add it to the FusionCharts.js:

 

--- FusionCharts.js	2008-04-25 14:22:38.000000000 -0700

+++ FusionCharts.js-NEW	2008-04-25 14:22:35.000000000 -0700

Please?
