wildcards in filenames

[Alan Thomas]

        Forgive me, as I have no experience with Unix, and this might be the 
source of my problem. . . . How do I specify that I only want, e.g., HTML files 
that begin with a certain letter from a directory?   

        Putting "/l*.htm" at the end of the URL did not work:

Warning: wildcards not supported in HTTP.

Putting l*.htm after the URL (separated with a space) did not work either.  

                                                Thanks, Alan
