I'm not sure if this is the same question, but when I try 
to download 
<http://publibn.boulder.ibm.com/doc_link/en_US/a_doc_lib/aix>
assem/alangref/about.htm
I get multiple copies of the website...
These are the directories:
C:\My Web Sites\AIX_5_1
\publibn.boulder.ibm.com\doc_link\en_US\a_doc_lib
C:\My Web Sites\AIX_5_1
\publibn.boulder.ibm.com\doc_link\en_US\a_doc_lib_
C:\My Web Sites\AIX_5_1
\publibn.boulder.ibm.com\doc_link\en_US\a_doc_lib__
C:\My Web Sites\AIX_5_1
\publibn.boulder.ibm.com\doc_link\en_US\a_doc_lib___
C:\My Web Sites\AIX_5_1
\publibn.boulder.ibm.com\doc_link\en_US\a_doc_lib____
and it continues...
