If your web browser  giving you an error message/number that you are not familiar
with feel free check  list  codes see what  means.
HTML Error codes:
200 - OK - Successful transmission. This not an error. The file you requested
was found, here is.
201 - Created - The request has been fulfilled  resulted  a new resource
being created. The newly created resource can be referenced by  URL(s) returned URL-header field response, with most specific URL for
the resource given by a Location header field.
202 - Accepted - The request has been accepted  processing, but the
processing has not yet completed.
203 - Non-Authoritative Information - The returned META information the

information send back.
206 - Partial Content - you requested a range bytes file, here
they are.
This new HTTP/1.1
300's - Redirected requests are those with other codes 300s. The most
common cause these requests that user has incorrectly requested a directory name without trailing slash. The server replies with a redirection
("you probably mean following") user then makes a second connection get correct document (although usually browser does it
automatically without user's intervention or knowledge). If you have a large number of 300 level result codes your logs, you have
probably specified links without trailing "/" (slash).
Here are most common 300 Error Codes:
300 - Multiple Choices - The requested source available at one or more
locations a preferred location could not be determined via content negotiation.
301 - Moved Permanently - The requested resource has been assigned a new
permanent URL any future references resource should be done using one of returned
URLs.
302 - Moved Temporarily - The requested resource resides temporarily under a
new URL. Redirection a new URL. The original page has moved. This not an error, most browsers invisibly fetch new page upon seeing result.
303 - See Other - The requested resource resides under a different URL and
should be accessed using a Get method  that resource.
304 - Not Modified - If client has performed a conditional GET request and
access allowed, but document has not been modified since date and time specified If-Modified-Since field, server responds with this
status code and does not send an Entity-Body client. Use local copy. This means that copy of file web server not newer than the
copy which your web browser or proxy server has cached locally, so there's no point sending file again. This not an error. The file hasn't changed
since last time you asked it, so I'm not going send again.
Here are most common 400 Error Codes:
400 - Bad Request - The request could not be understood by server due to
it having a malformed syntax. Bad request was made by client.
401 - Unauthorized - The request requires user authentication. The response
must include a WWW-Authenticate header field containing a challenge applicable requested source. The user asked a document but did not
provide a valid username or password.
402 - Payment Required - This code not currently supported, but reserved
for future use.
403 - Forbidden - The server understood request but refusing perform
the request because of an unspecified reason. Access explicitly denied document. (This might happen because web server doesn't have read
permission file you're requesting.) The server refuses send you file. Maybe permission has been explicitly turned off.
404 - Not Found - The server has not found anything matching requested
URL. This file doesn't exist. What you get if you give a bad URL your browser. This can also be sent if server has been told protect the
document by telling unauthorized people that doesn't exist.
404 errors are result of requests pages which do not exist, and can
come from a mistyped URL, a bookmark which points a file no longer there, search engines looking a robots.txt (which used mark pages you don't
want indexed by search engines), people guessing filenames, bad links from
your site or other sites, etc.
405 - Method Not Allowed - The method specified request line not
allowed resource identified by requested URL.
406 - None Acceptable - The server has found a resource matching the
request URL, but not one that satisfies conditions identified by Accept
and Accept-Encoding request headers.
407 - Proxy Authentication Required - This code reserved future use. It is
similar 401 (Unauthorized) but indicates that client must first authenticate itself with a proxy. HTTP/1.0 does not provide a means proxy
authentication.
408 - Request Timeout - The client did not produce a request within time
the server was prepared wait.
409 - Conflict - The request could not be completed due a conflict with the
current state of resource.
410 - Gone - The requested resource no longer available at server and
no forwarding address known.
411 - Authorization Refused - The request credentials provided by client
were rejected by server or insufficient grant authorization access the
resource.
Here are most common 500 (and beyond) Error Codes:
500 - Internal Server Error - The server encountered an unexpected condition
that prevented from filling request. Something went wrong with web server and couldn't give you a meaningful response. There usually nothing
that can be done from browser end fix error; server administrator will probably need check server's error log see what
happened. This often error message for a CGI script which has not been properly coded.
501 - Not Implemented - The server does not support functionality required
fulfill request. Application method (either GET or POST) not
