Summary
When a user attempts to access a running Internet Information Service through HTTP or file transfer protocol (FTP)
IIS returns a digital code indicating the status of the request. The status code is recorded in
IIS logs may also be displayed in a web browser or an FTP client. Status Code can indicate whether a specific request is
If the request is successful, the exact cause of the Request failure can be revealed.
More information
The location of the log file. By default, IIS places its log files in % WINDIR/system32/logfiles
Folder. Each WWW site and FTP site have a separate directory under this directory. In default status
Every day, log files are created under these directories and named by date (for example, exyymmdd. Log)
.
1xx-Information prompt
These status codes indicate temporary responses. Before receiving a regular response, the client should prepare to receive one or more 1xx responses.
.
100-continue.
101-switch protocol.
2XX-success
This type of Status Code indicates that the server successfully accepts client requests.
200-OK. The client request is successful.
201-created.
202-accepted.
203-non-authoritative information.
204-NO content.
205-Reset content.
206-part of content.
3xx-redirection
The client browser must perform more operations to implement the request. For example, a browser may have to request different pages on the server.
Or repeat the request through the proxy server.
301-moved permanently the document requested by the customer is elsewhere. The new URL is provided in the location header,
The browser should automatically access the new URL.
302-found is similar to 301, but the new URL should be treated as a temporary alternative, rather than permanent. Note,
In http1.0, the corresponding status information is "moved temporatily". When this status code appears, the browser can automatically
Access the new URL, so it is a very useful status code. Note that this status code can be replaced with 301 sometimes.
. For example, if the browser mistakenly requests http: // host /~ User (with a slash missing), some servers return
301, and some return 302. Strictly speaking, we can only assume that the browser will automatically rebind only when the original request is get.
Direction. See 307.
303-see other is similar to 301/302. The difference is that if the original request is post, the location header
The specified redirection target document should be extracted through get (New in HTTP 1.1 ).
304-not modified the client has a buffered document and sends a conditional request (generally, if-
The modified-since header indicates that the customer only wants documents updated on a specified date ). The server tells the customer that the original buffered document
You can continue to use it.
305-use proxy the document requested by the client should be extracted by the proxy server specified in the location header (HTTP
1.1 New ).
307-temporary redirect and 302 (found) are the same. Many browsers mistakenly respond to 302 responses.
Redirection. Even if the original request is post, it can only be redirected when the response of the POST request is 303.
For this reason, HTTP 1.1 adds 307 to clear the region status code: When a 303 response occurs,
The browser can follow the redirected get and post requests. If the request is a 307 response, the browser can only follow the weight of the GET request.
Targeting. (New HTTP 1.1)
