Often the trace will put out many thousands of records,
whereas, for an HTML web page, usually no more than 5-10,000 is practical.
The trace records filter can limit the number of lines to the last
Usually, if you are looking for an error, it will occur near the end of the parse anyway
and this becomes a handy way to clip off the initial records.
