I believe that at some point, a bare semi-colon was/is considered as an alternative to 
"&", to separate post parameters.
So with the query string above, you probably have one parameter named "value" with a value 
of "f1", then another parameter named "2011-10-09" with value null, then a parameter named 
"21" with value null, etc...

There might be an option to Apache::Request to avoid this.
