- This article applies to all MD ICAP versions
Summary:
This article explains the behavior of the ICAP Server when processing a batch of files, particularly when one of the files fails during submission to the MetaDefender Core (MD-Core) engine.
Behavior Overview
When the ICAP Server receives a request that contains multipart form, it processes the request in the following sequence:
- Batch Initialization
- The ICAP Server initializes a new batch to group the incoming files.
- Parallel Submission to MD-Core
- Each part are sent to MD-Core concurrently using the API:
POST /file
Note: The default maximum concurrency is 5.
- If a File Fails During Submission from MD Core
- When a file fails to submit, the ICAP Server will trigger a batch scan cancellation.
- Note: Batch scan cancellation currently only occurs when a file POST request to MD Core fails. Other failure scenarios are under review for future enhancements and are not yet supported.
