(*sigh*, so no I have to actually read your code...)

|  (let-values ;;(((url) (send urlbox get-value))
|   (((sin sout) (tcp-connect url 80))
|    ((html-start) (regexp "Content-Type:.*")))

Your indentation is screwed here...

|   (fprintf sout "GET http://www.~s HTTP/1.0~n~n" url)

Are you sure you want a "~s" there?  If url is a string, then the
string which is sent includes double-quote characters.

|   (do ((line (read-line sin) (read-line sin)))
|       ((not (regexp-match html-start line))))
|         ^^^

Isn't this supposed to be the other way?
