错误信息分析（英文）
Decoding Error Messages

As you surf the Net, you will undoubtedly find that at times you can''t access
certain websites. Why, you make wonder? Error messages attempt to explain the reason.
Unfortunately, these cryptic* messages baffle* most people. We''ve deciphered* the
most common ones you may encounter.

400 - Bad Request
Problem: There''s something wrong with the address you entered. You may not be
authorized* to access the web page, or maybe it no longer exists.
Solution: Check the address carefully, especially if the address is long. Make
sure that the slashes are correct (they should be forward slashes) and that all the
names are properly spelled. Web addresses are case sensitive, so check that the names
are capitalized in your entry as they are in the original reference to the website.

401 - Unauthorized
Problem: You can''t access a website, because you''re not on the guest list, your
password is invalid or you have entered your password incorrectly.
Solution: If you think you have authorization, try typing your password again.
Remember that passwords are case sensitive.

403 - Forbidden
Problem: Essentially the same as a 401.
Solution: Try entering your password again or move on to another site.

404 - Not Found
Problem: Either the web page no longer exists on the server or it is nowhere to
be found.
Solution: Check the address carefully and try entering it again. You might also

not uncommon for pages to change their addresses when a website is redesigned.) To
get to the home page of the site, delete everything after the domain name and hit
the Enter or Return key.

503 - Service unavailable
Problem: Your Internet service provider (ISP) or your company''s Internet
connection may be down.
Solution: Take a stretch, wait a few minutes and try again. If you still have
no luck, phone your ISP or system administrator.

Bad file request
Problem: Your web browser may not be able to decipher the online form you want
to access. There may also be a technical error in the form.
Solution: Consider sending a message to the site''s webmaster, providing any
technical information you can, such as the browser and version you use.

Connection refused by host
Problem: You don''t have permission to access the page or your password is
incorrect.
Solution: Try typing your password again if you think you should have access.

Failed DNS lookup
Problem: DNS stands for the Domain Name System, which is the system that looks
up the name of a website, finds a corresponding number (similar to a phone number),
then directs your request to the appropriate web server on the Internet. When the
