> X11 colors
> Some browsers reconize X11 color names. In this table (generated by x11-colors.pl) one can check if the used browser recognizes the X11 colors, and if they are correctly recognized. Each entry is made of a color swatch created using the X11 name, containing XX in the RGB color equivalent, followed by the name used and RGB equivalent. This means that if the browser recognizes correctly the X11 color name the XX won't be visible. For example, the X11 color gray uses RGB bebebe, while the W3C standard uses 808080, so the XX should be visible

> Overloading the `ACTION` Parameter
> One way to make sure that data gets passed along by a form is to add the `cgi` variable information to the `ACTION` parameter of the `FORM` statement. The value of `ACTION` is a hyperlink, so it can take CGI parameters in the usual way. This example invokes `MakeC.cgi`, with the variables `Name, ColorChoice,` and `Horsepower` equal to `Kurt, Blue,` and `0`, respectively, when the user submits the form: <FORM ACTION="MakeC.cgi?Name=Kurt&ColorChoice=Blue&Horsepower=0">

HTTP |  | top

> HTTP status codes

> HTTP status codes
> Code | Meaning | Details
> --- | --- | ---
> 1xx - Informational
> 100 | Continue | The initial part of the request has been received and the client may continue with its request
> 101 | Switching Protocols | The server is complying with a client request to switch protocols to the one specified in the Upgrade header field
> 2xx - Client request successful
> 200 | Ok (HTTP 1.0) | The client's request was successful, and the server's response contains the requested data
> 201 | Created | This status code is used whenever a new URI is created. With this result code, the Location header is given by the server to specify where the new data was placed
> 202 | Accepted | The request was accepted but not immediately acted upon. More information about the transaction may be given in the entity body of the server's response. There is no guarantee that the server will actually honor the request, even though it may seem like a legitimate request at the time of acceptance
> 203 | Non-Authoritative Information | The Information in the entity header is from a local or third-party copy and not from the original server
> 204 | No Content | A status code and header is given in the response, but there is no entity body in the response. This is a useful code for an imagemap handler to return when the user clicks on useless or blank area of an image
> 205 | Reset Content | The browser should clear the form used for this transaction for additional input. Appropriate for data-entry CGI applications
> 206 | Partial Content | The server is returning partial data of the size requested. Used in response to a request specifying a Range header
> 3xx - Client request redirected, further action necessary
> 300 | Multiple Choices | The requested URI refers to more than one resource. For example, the URI could refer to a document that has been translated into many language. The entity body returned by the server could have a list of more specific data about how to choose the correct resource
> 301 | Moved Permanently | The requested URI is no longer used by the server, and the operation specified in the request was not performed. The new location for the requested document is specified in the Location header. All future requests for the document should use the new URI
> 302 | Moved Temporarily (HTTP 1.0) | The requested URI has moved, but only temporarily. The Location header points to the new location. Immediately after receiving this status code, the client should use the new URI to resolve the request, but the old URI should be used for all future requests
> 303 | See Other | The requested URI can be found at a different URI (specified in the Location header) and should be retrieved by a GET on that resource
> 304 | Not Modified (HTTP 1.0) | This is the response code to an If-Modified-Since header, where the URI has not been modified since the specified date. The entity body is not sent, and the client should use its own local copy
> 305 | Use Proxy | The requested URI must be accessed through the proxy in the Location header
> 4xx - Client request incomplete
> 400 | Bad Request (HTTP 1.0) | This response code indicates that the server detected a syntax error in the client's request
> 401 | Unauthorized (HTTP 1.0) | The result code is given along with the WWW-Authenticate header to indicate that the request lacked proper authorization, and the client should supply proper authorization when requesting this URI again
> 402 | Payment Required | This code is not yet implemented in HTTP
> 403 | Forbidden (HTTP 1.0) | The request was denied for a reason the server does not want to (or has no means to) indicate to the client
> 404 | Not Found (HTTP 1.0) | The document at the specified URI does not exist
> 405 | Method Not Allowed | This code is given with the Allow header and indicates that the method used by the client is not supported for this URI
> 406 | Not Acceptable | The URI specified by the client exists, but not in a format preferred by the client. Along with this code, the server provides the Content-Language, Content-Encoding, and Content-Type headers
> 407 | Proxy Authentification Required | The Proxy server needs to authorize the request before forwarding it. Used with the Proxy-Authenticate header
> 408 | Request Time-out | This response code means the client did not produce a full request within some predetermined time (usually specified in the server's configuration) and the server is disconnecting the network connection
> 409 | Conflict | This code indicates that the request conflicts with another request or with the server's configuration. Information about the conflict should be returned in the data portion of the reply
> 410 | Gone | This code indicates that the requested URI no longer exists and has been permanently removed from the server
> 411 | Length Required | The server will not accept the request without a Content-Length header supplied in the request
> 412 | Precondition Failed | The condition specified by one or more If... headers evaluated to false
> 413 | Requested Entity Too Large | The server will not process the request because its entity body is too large
> 414 | Request-URI Too Long | The server will not process the request because its request URI is too large
> 415 | Unsupported Media Type | The server will not process the request because its entity body is in an unsupported format
> 5xx - Server errors
> 500 | Server Error (HTTP 1.0) Internal Server Error (HTTP 1.1) | This code indicates that a part of the server (for example, a CGI program) has crashed or encountered a configuration error.
> 501 | Not Implemented (HTTP 1.0) | This code indicates that the client requested an action that cannot be performed by the server
> 502 | Bad Gateway (HTTP 1.0) | This code indicates that the server (or proxy) encountered invalid responses from another server (or proxy)
> 503 | Out of resources (HTTP 1.0) Service Unavailable (HTTP 1.1) | This code means that the service is temporarily unavailable, but should be restored in the future. If the server knows when it will be available again, a Retry After header may also be supplied
> 504 | Gateway Time-out | This response is like 408 (Request Time-out) except that the gateway or proxy has timed out
> 505 | HTTP Version not supported | The server will not support the HTTP protocol version used in the request
