Configure inbound HTTP request chunking

Inbound HTTP request chunking is used to eliminate the restriction on messages greater than 10MB. The 10MB restriction is set because the entire message is buffered in the controller before the HTTP request is dispatched to the servant, therefore, the controller may fail with an out of memory condition when multiple large HTTP messages are processed simultaneously. With chunking enabled, the message is broken up into smaller pieces before it is processed by the Web container and application. As a result, only one small chunk is buffered in memory at a time in the controller thus greatly reducing the amount of memory consumed by large HTTP messages. Applications do not require changes to enable inbound HTTP chunking.

Overview

Inbound HTTP request chunking, is configured at the Web container transport chain level. You can configure each Web container chain to enable or disable chunking. When chunking is enabled for a particular chain, you can also configure the maximum chunk size for chunking enabled for each chain.

The chains that host the Integrated Solutions console have chunking enabled by default, while all other Web container chains have chunking disabled by default.
