[Bug-wget] How to get only updated pdf files from a ColdFusion site?

[Pierre Fortin]

Hi,

No idea how I get into these subtle issues that seem to defy logic...

I grabbed pdf files with:
$ wget -r -nd -A \*pdf http://www.ncrealtors.org/sampleforms.cfm

When I re-issue the command, hoping for just updated files, wget
re-downloads everything as filename.1, then deletes that file.  Any idea
how to prevent these useless downloads?

Thanks,
Pierre

Here's the console output...

$ wget -r -nd -A \*pdf http://www.ncrealtors.org/sampleforms.cfm
