Daniel,
Well I'm sure the Unidata experts will have the definitive answer, but
I'll go out on a limb and guess that the answer is no since the
ldmd.conf file lists the syntax of the ALLOW statement as:
allow <feedset> <hostname pattern>
whereas the syntax of the REQUEST statement is:
request <feedset> <pattern> <hostname pattern>
Notice there is no <pattern> argument to the the ALLOW that would allow
you to limit the feedtype(s) as in the REQUEST. This also corresponds to
what is in the 7/2001 LDM5 Site Manager's Guide on p. 24.
Now this is LDM v5 and maybe the ALLOW has been enhanced in LDM v6, but I
don't remember seeing anything about that.
But this might be a nice feature to have in certain circumstances I
suppose.
