Study Notes
HTML Form Inputs
- ACTION attribute specifies the location of the CGI script that processes form data.
- Common HTML form inputs include:
- Text Fields: For single-line text input.
- Radio Buttons: To select one option from multiple choices.
- Checkboxes: To select multiple options.
- Submit Button: For sending form data.
Form Tag Attributes
- Contains several attributes, including:
- NAME: Differentiates one form from another.
- ACTION: Specifies where the form data is sent.
- METHOD: Determines how data is sent (e.g., GET, POST).
Single-line Text Entry
- Allows small text inputs such as names or emails.
- Syntax includes attributes like:
- TYPE="text": Defines the field as a single-line input.
- SIZE="40": Displays 40 characters.
- MAXLENGTH="30": Limits input to 30 characters.
- NAME: Identifies the field for data processing.
Multi-line Text Entry
- For larger text input, uses the <textarea> tag.
- Attributes include:
- NAME: Identifies the textarea field.
- COLS="50": Sets width to 50 characters.
- ROWS="5": Sets height to 5 rows.

,
-
- Reduces reliance on elements for structure.
HTTP and TCP/IP
- HTTP is built on the TCP/IP protocol, requiring a TCP connection to exchange requests/responses.
- HTTP/1.0 opens a separate TCP connection for each request, which is less efficient than persistent connections.
HTTPS
- Stands for Hypertext Transfer Protocol over Secure Socket Layer, providing secure data transmission.
- Utilizes SSL/TLS for encryption, ensuring safety when transmitting personal information.
- Websites require an SSL certificate for HTTPS, typically issued by a Certificate Authority.
HTTP Messages
- Consist of requests and responses, with formats defined in HTTP/1.1 and HTTP/2.
- Requests include:
- HTTP method (e.g., GET, POST), resource path, version, optional headers, and body for data submission.
- Responses consist of:
- Protocol version, status code, status message, headers, and possibly a body with fetched resource.
Connection Types
- HTTP supports nonpersistent and persistent connections:
- Nonpersistent connections close after the server sends the requested object.
- Persistent connections allow for multiple requests/responses over a single TCP connection, improving efficiency.
