Here is one possible solution:

sed -n -e 's|\(^.*://[a-z.-]*\)/.*|\1|p'  file

Probably, all your problem are in forgetting to put back delimiter '/'
It works for me:

> cat > try.t

^C
>nawk -F/ '{ print $1"/"$2"/"$3; }' try.t

>sed -n -e 's|\(^.*://[a-z.-]*\)/.*|\1|p' try.t

The tag does not works. Whithout tag it works:

c> sed -n  's|^.*://[a-z.-]*/|lll_|p' try.t
lll_squid-internal-static/icons/anthony-xpm.gif
lll_img/br.png
lll_css/print
lll_infoce...terwarning.css
lll_img/navbar/1/corner.gif
lll_pdg/asd/bin.jpg
lll_qwer/gft.js
>
c> alias sed
bash: alias: `sed' not found
> which sed
/bin/sed

Any idea why?

I think this one is ok for you.

awk 'BEGIN{FS="/"}{print$1"/"$2"/"$3}' filename
