Local/Remote Resources

www.example.com/path1 resMerge:///User/xxx/test.json
www.example.com/path2 resMerge://https://www.xxx.com/xxx/params.json
# Editing a temporary file
www.example.com/path3 resMerge://temp/blank.json

Note: Response Size Limit

To ensure processing performance, resMerge enforces a default size limit for response content.

• Limit Specification: The automatic merge processing is only applied to responses with a body size less than 2MB. Responses exceeding this size will be skipped.
• How to Override: If you need to handle larger responses (e.g., for downloading files or processing large data interfaces), you can explicitly enable this capability by adding the following directive to your matching rule:

pattern enable://resMergeBigData

# or
www.example.com/path1 resMerge:///User/xxx/test.json lineProps://enableBigData

Once enabled, resMerge will attempt to process larger response volumes. Please note that this may increase memory consumption and processing time.
