Cracking documents and spidering URLs are both big, big problems. PDF is a horrid mess, as are old versions of MS Office. Proxies, logins, cookies, all sort of issues show up with fetching URLs, along with a fun variety of misbehaving servers. I remember crashing one server with 25 GET requests before we implemented session cookies in our spider. That used all that DB connections and killed the server. If you need to do a lot of spidering and parse lots of kinds of documents, I don't know of an open source solution for that. Products like Ultraseek and the Googlebox are about your only choice. wunder -- Walter Underwood Search Guru, Netflix Former Architect for Ultraseek
