Question by Joel B. · Sep 11, 2013 at 02:22 PM · business transaction

Web Requests - Null Parameter Values

Hello,

Customer is extracting a value from a Web Request parameter (e.g. UserID=123456).  Customer claims that some web requests occasionally do not have an assigned value.

Will the purepaths for the transactions that have a null parameter value still be visible as their own split in the business transaction?

Thanks,

Joel B

You could try to setup a filter with "not regex" and try something like ".+".

That would in theory only let purepaths through that didn't contain any username.

I guess contains "" would do the same thing but I don't think I'm answering your question :/

Unfortunately not, we are experiencing this at my customer right now.  There is an RFE to allow null values through here: Possibility to have null splitting values in business transactions

Thanks, Rick...

Follow up question:

Do you know if I look at the details of the purepath in the call tree, where I usually see "UserID=12345", if the parameter was null, would it still show up as USERID=&NEXTPARAM?  (Does that make sense?)

Depends.  The parameter can be null as in "UserID=" (in this case you will see what you say there), or null as in doesn't exist for that request, in which case you won't see anything.
