QueryString variable to capture URL parameter does not work if parameter name is uppercase in URL

[rohitsane]

I set up a Querystring parameter to capture the URL parameter for the parameter name "intcmp". In the below Example1, I am fetching the result as expected. I am retriving "testvalue" in my Sitecatalyst variable as expected.

Example1: xyz.com/?intcmp=testvalue

The issue arises when someone visits the URL with the parameter name in uppercase; I am not able to retrive this value.

The Example2 does not work.

Example2: xyz.com/?INTCMP=testvalue

Any suggested solutions? [Adobe App Measurement library is used and I have overwritten the Util.getQueryParam function to the old getQueryParam in sCode and everything seems to work fine, so that's unlikely the cause]

Sounds like you need to turn on lower case query string parameters. 

By default Tealium will not lowercase the querystrings:

However you can override this setting and get the results you are looking for:

To override, you need a JavaScript Extension scoped to PreLoader with the following code:

window.utag_cfg_ovrd = window.utag_cfg_ovrd || {};
window.utag_cfg_ovrd.lowerqp = true;

Now you just map the querystings to any evar or sprop like you normally would in tag mappings.

The setup I am referring to does not use Adobe's code for getting the query string parameters, it use's Tealium.

Does that answer you question?

Thanks @brian_kranson for this solution.

One quick question: Will this extension lowercase only the query parameter name(INTCMP) or even the value(testvalue) passed in the parameter? [we are passing case sensitive values to the parameters]

@rohitsane

Only the name.

If you want to lowercase the values we have an extension for that:
