Local/Remote Resources

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

Note: Request Size Limit

To ensure processing performance, reqMerge enforces a default size limit for request content.

• Limit Specification: The automatic merge processing is only applied to requests with a body size less than 2MB. Requests exceeding this size will be skipped.
• How to Override: If you need to handle larger requests, you can explicitly enable this capability by adding the following directive to your matching rule:

pattern enable://reqMergeBigData

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

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