Setting HTTP request/response header limits

Edge for Private Cloud v. 4.16.09

The Edge Router and Message Processor have predefined limits to the size of request/response headers and to the line size.

For the Router, which handles incoming requests from your APIs, edit the following properties in /<inst_root>/apigee/customer/application/router.properties to change these default values:

conf_router_HTTP.request.line.limit=4k
conf_router_HTTP.request.header.limit =8k
conf_router_HTTP.response.line.limit=4k
conf_router_HTTP.response.header.limit =8k

If that file does not exist, create it.

You must restart the Router after changing these properties:

> /<inst_root>/apigee/apigee-service/bin/apigee-service edge-router restart

For the Message Processor, which handles outgoing requests to your backend services, edit the following properties in /<inst_root>/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:

> /<inst_root>/apigee/apigee-service/bin/apigee-service edge-message-processor restart
