Name

DISABLE_CHUNKING

Possible Values

"true", "false"

Default Behavior

false

Scope

axis2

Description

If you set this to true, it disables HTTP chunking for outgoing messages. Instead, the ESB builds the message to calculate the content length and then sends the particular message to the backend with the content length (e.g., Content-Length: 25).

You can use this parameter if the client sends the request with HTTP chunking (i.e., with Transfer Encoding:chunked) although you need to send the message without HTTP chunking to the backend, or if you need to modify the message payload, which the client receives before sending it to the backend.

Warning

This property might decrease performance since the messages get built per each invocation. Also, this property does not affect Callout mediators, whose chunking must be disabled separately.

Example

Code Block
<property name="DISABLE_CHUNKING" value="true" scope="axis2"/>

...

Name

FORCE_POST_PUT_NOBODY

Possible Values

"true", "false"

Default Behavior

false

Scope

axis2

Description

This property allows to send a request without a body for POST and PUT HTTP methods.

Applicable only for HTTP Passthrough transport.

Example

Code Block
<property name="FORCE_POST_PUT_NOBODY" value="true" scope="axis2" type="BOOLEAN"/>

Anchor
FORCE_HTTP_CONTENT_LENGTH
FORCE_HTTP_CONTENT_LENGTH
FORCE_HTTP_CONTENT_LENGTH

Name

FORCE_HTTP_CONTENT_LENGTH

Possible Values

"true", "false"

Default Behavior

false

Scope

axis2

Description

If the request sent by the client contains the ‘Content-Length’ header, this property allows the ESB to send the request with the content length (without HTTP chunking) to the back end server.

You should set this to true in scenarios where the backend server is not able to accept chunked content. For example, in a scenario where a pass-through proxy is defined and the backend does not accept chunked content, this property should be used together with the COPY_CONTENT_LENGTH_FROM_INCOMING property, to simply add the content length without chunking.

When HTTP 1.1 is used, this property disables chunking and sends the content length. When HTTP 1.0 is used, the property only sends the content length.

Warning

This property can cause performance degradation, and thereby, you should only use it with message relay. If you set this to true, the ESB forwards the content length coming from the client request to the backend without building the message and calculating the content length. Since the message doesn’t get build, using these properties will perform better than using DISABLE_CHUNKING. However, if you change the receiving payload before sending it to the backend, then having this property will result in an error due to a content length mismatch.

Example

Code Block
languagexml
<property name="FORCE_HTTP_CONTENT_LENGTH" scope="axis2" value="true"></property>

...

Name

COPY_CONTENT_LENGTH_FROM_INCOMING

Possible Values

"true", "false"

Default Behavior

false

Scope

axis2

Description

This property allows the HTTP content length to be copied from an incoming message. It is only valid when the FORCE_HTTP_CONTENT_LENGTH property is used. The COPY_CONTENT_LENGTH_FROM_INCOMING avoids buffering the message in memory for calculating the content length, thus reducing the risk of performance degradation.

Example

Code Block
languagexml
<property name="COPY_CONTENT_LENGTH_FROM_INCOMING" value="true" scope="axis2"/>
