I've found many entries on the subject of filtering IIS logs, with people saying X has worked. However, I'm not able to get it fully working. If I copy an IIS log that should be filtered to the server and import it manually it works (as far as I can tell, I only went to preview) but if I use a UF from a server 2003 (so older UF version) box, to the Splunk server on windows 2012 (6.6.3), it doesn't get filtered. Any help here?
Page1 and Page2 are only part of the cs-uri-stem (that's its name in the IIS logs, but Splunk seems to turn it into csuristem), instead they're like companyname.product.page1/service.asmx or companyname.product/page2.asmx
I've tried placing the props and transforms files on both the system/local directory of the UF and the Splunk receiver, restarted both and it continued to process the unwanted pages.
I understand that it looks like UF itself can't filter these lines, but that it processes them sufficiently to get past props and transforms on the Splunk machine. I assume there's a way I can make Universal Fowarder send the logs RAW and the Spunk box will go "OH, W3C, process normally," but how do I do that?

Filtering out these pages is absolutely critical as they're hundreds of thousands of internal calls that would spam the Splunk logs, and overwhelm our 500mb/day limit that I need to stay under for proof of concept.
This works as is. Just have to make sure to place the file in the right spot, restart the UF and WAIT. It took a little while for events with the correct filter to come in. I'm guessing there was a queue somewhere between sending to Splunk and applying the props/transforms.
