An extension for easy match/replace of tokens/CSRF/anything using regex. Handles XML and JSON. By default, SWAPPER sends a request to obtain the token/value every 4 minutes. You can change the time to request a new token. Disabling auto-refresh will request a token for each request(needed every now and again...). A new value will be requested for each interval. Can pull multiple patterns out of response and set multiple patterns to replace.
        
HOW TO USE:

1. Right-click on any request in Target/History
2. Select "Send to Swapper" to populate fields
3. Set up regex patterns for token extraction/replacement
4. Test your configuration
5. Enable tools and auto-refresh as needed

To check regex matches, Test Token Request will send request and display regex hit/miss in status box. For the request, go to request you want to check in Proxy history/History/Target, right click and under extensions, select `Test Request Regex`. Resulting hit/miss will show in status box.
