Introduction
Your Web server thinks that the URL provided by the client (e.g.
your Web browser or our CheckUpDown robot) is not specific enough, and a
further selection needs to be made from a number of choices.
This is typically the case where the URL represents a high level
grouping of which lower level selections need to be made e.g. a directory
within which the user must select a particular file to access.
300 errors in the HTTP cycle
Any client (e.g. your Web browser or our CheckUpDown robot) goes
through the following cycle when it communicates with your Web server:
- Obtain an IP address from the IP name of your site (your site
URL without the leading 'http://'). This lookup (conversion of IP name to IP
address) is provided by domain name servers (DNSs).
- Open an IP socket connection to that IP address.
- Write an HTTP data stream through that socket.
- Receive an HTTP data stream back from your Web server in
response. This data stream contains status codes whose values are determined by
the HTTP protocol. Parse this data stream for status codes and other useful
information.
This error occurs in the final step above when the client
receives an HTTP status code that it recognises as '300'.
Resolving 300 errors - general
The first thing you should do is check your URL in a Web
browser. If you see some kind of Web page prompting you for further
action/choices, then your URL as it stands is not detailed enough for the Web
server to process.
Resolving 300 errors - CheckUpDown
You should never see this error on your CheckUpDown account if
you gave us a top-level URL (such as www.isp.com) to check. If it does
occur for a top-level URL, it is highly likely that your Web server software
has been incorrectly programmed or configured. If you have given us a low-level
URL (such as www.isp.com/products/index.html) to check, then it is
likely that this URL is not accessible even via a Web browser.
The first thing you should do is check your URL in a Web
browser. If you see a sensible Web page, then it may indicate a defect in our
software. If however you see some kind of Web page prompting you for further
action/choices, then your URL is not suitable for us to check, because our
system can not possibly make this kind of choice.
Please contact us directly (email preferred) whenever you
encounter 300 errors. Only we can resolve them for you. If there is a defect in
our software we will fix it. If however your URL is fundamentally unsuitable
for us to use, you need to change it on your CheckUpDown account (start by
clicking the 'Manage' button). |
