Usage Limitations
Route Configuration
To ensure that the instance can correctly forward data to the backend service node, it is necessary to ensure that the firewall/route of the backend service node can allow access to the corresponding network segment. Otherwise, it may cause the host to fail to provide services normally.
You can see the network segments of each region in the Public Service Network Segment.
HTTP Message Header Limitations
The default message header size of CLB is 8K. When configuring, you need to ensure that the HTTP message header size does not exceed 8K. Otherwise, it may make CLB unable to work normally.
