You could use a regular expression to extract the fields. Something like this:

props.conf

[your_sourcetype]
EXTRACT-fields=^[\d\-]+) [\d:]+ (?<FIELD_1>\d+) (?<clientip>[\d\.]+) (?<domain>\S+) Filter\-ID==(?<filter_id>\S+) "(?<url_category>[^"]+)" (?<url>\S+) (?<status>\d+)

I found that transaction may be up to 2kB. Very hard to write a regex to cover all of them. However your answer is Ok. Thanks.
