Configure advanced break points:

1. Configure conditional break points:

   • Break on specific URLs or patterns
   • Break on specific HTTP methods
   • Break on request/response headers
   • Break on request/response body content

2. Set up break point rules:

   • Create complex break point conditions
   • Combine multiple conditions
   • Configure break point scope
   • Set up break point timing

Advanced request manipulation:

1. Modify request components:

   • Edit headers on-the-fly
   • Manipulate cookies
   • Modify request body content
   • Change HTTP methods

2. Use specialized editors:

   • Structured editors for JSON/XML
   • Hex editor for binary content
   • Syntax highlighting for various formats
   • Format validation and beautification

Configure advanced traffic filtering:

1. Set up filter criteria:

   • Filter by request/response size
   • Filter by status code
   • Filter by content type
   • Filter by request method
   • Filter by response time

2. Create complex filters:

   • Combine multiple filter conditions
   • Use regular expressions for filtering
   • Save and reuse filter configurations
   • Export filtered results

Advanced traffic analysis techniques:

1. Analyze traffic patterns:

   • Identify request sequences
   • Detect authentication flows
   • Map application functionality
   • Discover hidden endpoints

2. Use specialized analysis:

   • Compare requests and responses
   • Analyze parameter usage
   • Detect information leakage
   • Identify security patterns

Configure HTTP/2 support:

1. Enable HTTP/2 support:

   • Go to Tools > Options > Network
   • Enable HTTP/2 support
   • Configure HTTP/2 settings

2. HTTP/2-specific features:

   • View HTTP/2 streams
   • Analyze HTTP/2 headers
   • Test for HTTP/2-specific vulnerabilities
   • Handle HTTP/2 server push

Work with HTTP/3 (QUIC):

1. Configure HTTP/3 support:

   • Install required add-ons
   • Configure HTTP/3 settings
   • Set up QUIC parameters

2. HTTP/3-specific testing:

   • Test for HTTP/3 compatibility
   • Analyze QUIC connections
   • Identify HTTP/3-specific security issues
   • Compare behavior across HTTP versions

Key add-ons for enhanced proxy functionality:

1. Replacer:

   • Automatically replace content in requests and responses
   • Configure match and replacement rules
   • Apply conditional replacements

2. Advanced Proxy Settings:

   • Configure additional proxy options
   • Set up specialized proxy behaviors
   • Customize proxy response handling

3. WebSockets:

   • Intercept and manipulate WebSocket connections
   • Analyze WebSocket traffic
   • Test WebSocket security

Create custom proxy scripts:

1. Script types:

   • HTTP Sender scripts
   • Proxy scripts
   • Targeted scripts

2. Script capabilities:

   • Modify requests and responses
   • Implement custom logic
   • Integrate with external tools
   • Automate complex workflows

Example proxy script for request modification:

// Add a timestamp header to all requests
function proxyRequest(msg) {
    var header = "X-Request-Timestamp";
    var timestamp = new Date().toISOString();
    msg.getRequestHeader().setHeader(header, timestamp);
    return true;
}

function proxyResponse(msg) {
    // Process responses if needed
    return true;
}
