Links not extracted!

[Tan Joo Geok]

Hello,

I am using the lwp-request sample program that comes with the libwww distribution to 
parse the content of various web sites.  I noticed that for certain web sites, the 
links fail to be extracted by lwp-request, e.g:

lwp-request -o links http://www.cpf.gov.sg
lwp-request -o links http://www.moe.edu.sg

Would appreciate if somebody can let me know why this is happening.  I have verified 
that both the above URLs contain a number of images and hyperlinks.

Thanks for the attention.
