So IIS logs are usually delimited by a space between every other field, however I have recently realized that when a certain field value contains a quotation mark in this example it would be the "cs_uri_query" field , the field value starting with a quotation mark grabs all the remaining rest of the log included as its value even though there would be spaces included in the value itself.
An example log of the problem from what I mean could be found bellow:
2021-05-15 14:02:58 11.11.11.11 GET /WebID/IISWebAgentIF.dll postdata="><script>foo</script> 55000 - 11.11.11.111 Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+5.1;+Trident/4.0) - 404 0 64 0 11.11.11.111:60754
My Transforms with field delimeter set as " " is as follows:
date time s-sitename s-computername s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs-version cs(User-Agent) cs(Cookie) cs(Referer) cs-host sc-status sc-substatus sc-win32-status sc-bytes cs-bytes time-taken X-Forwarded-For
