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

align="top" height=50 width=100>
When clicked, the image behaves like a submit button, returns name.x and name.y values with the coordinates that were clicked
<input type="reset" value="clear it">
A button that resets the form fields to initial values. value is the button caption
<input type="text" value="defaultvalue"
name="extext" size="10" maxlength="25">
A single line text input field. size is the visible width, maxlength the maximum number of characters returned
<input type="password"
value="defaultvalue" name="expsw">
A single line text input field, that displays asterisks instead of the characters
<input type="submit" value="Do this"
name="exsubmit">
Submits the form data to the server. value is the caption for the button
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">

Form tags
form textarea select option hidden radio checkbox image reset text password submit
<form method="get" action="/cgi-bin/worker"> ... </form>	Forms must be wrapped in these tags. method may be GET, where the data is sent in the URL, and POST, where data is sent trough environment variables
<textarea name="extext" rows="4" cols="50"> Default text </textarea>	Multi line text entry field
<select name="exsel" size="3"> <option value="opt1"> Option one <option value="opt2"> Option two <option selected value="opt3"> Option three </select>	Selects one (or more) element within a list of options
<input type="hidden" value="val" name="exhidden">	Hidden value, used to transmit persistent information to the server
<input type="radio" value="val1" name="radio1"> Value one<br> <input type="radio" value="val2" name="radio1" checked> Value two<br> <input type="radio" value="val3" name="radio1"> Value three	Exclusive select of one option within a group. Note that all the members of the group share the same name
<input type="checkbox" value="aval" name="excheck">	Multiple choice, boolean
<input type="image" src="example.jpg" name="eximage" align="top" height=50 width=100>	When clicked, the image behaves like a submit button, returns name.x and name.y values with the coordinates that were clicked

<input type="submit" value="Do this" name="exsubmit">	Submits the form data to the server. value is the caption for the button
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 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
