Edge for Private Cloud v4.18.05
The Edge Router and Message Processor have predefined limits to the size of request/response headers and to the line size.
Configure limits for the Router
For the Router, edit the following properties
in /opt/apigee/customer/application/router.properties
to change the default values:
# Request buffers # default: # conf_load_balancing_load.balancing.driver.large.header.buffers=8 16k # new value: conf_load_balancing_load.balancing.driver.large.header.buffers=8 32k # Response buffers # default: # conf_load_balancing_load.balancing.driver.proxy.buffer.size=64k # new value: conf_load_balancing_load.balancing.driver.proxy.buffer.size=128k
If that file does not exist, create it.
For conf_load_balancing_load.balancing.driver.large.header.buffers, the first
parameter specifies the number of buffers, and the second the size of each buffer. The buffers are
allocated dynamically and released after usage. These settings are only used if the request header
is more than 1 KB. For requests that have header request URI less than 1 KB, the large buffers
won't even be used.
For conf_load_balancing_load.balancing.driver.proxy.buffer.size, specify the size
of the response buffer.
The Edge Router is implemented using Nginx. For more on these properties, see:
- conf_load_balancing_load.balancing.driver.large.header.buffers
- conf_load_balancing_load.balancing.driver.proxy.buffer.size
You must restart the Router after changing these properties:
/opt/apigee/apigee-service/bin/apigee-service edge-router restart
Configuring limits for the Message Processor
For the Message Processor, which handles outgoing requests to your backend services, edit the
following properties in /opt/apigee/customer/application/message-processor.properties
to change these default values:
conf/http.properties+HTTPRequest.line.limit=7k conf/http.properties+HTTPRequest.headers.limit=25k conf/http.properties+HTTPResponse.line.limit=2k conf/http.properties+HTTPResponse.headers.limit=25k
If that file does not exist, create it.
You must restart the Message Processor after changing these properties:
/opt/apigee/apigee-service/bin/apigee-service edge-message-processor restart
