The Apache included with SPS has a default limit of ~8k characters for request URLs, and can be increased via the LimitRequestLine directive.
The web agent has a default request URL limit of 4096B. This can be adjusted via the web agent's MaxURLSize ACO parameter:
- MaxUrlSize
Specifies the maximum size (in bytes) of a URL that a Web Agent can handle. Because different web servers have different limitations on URL length, check the documentation from your web server vendor before setting this parameter.
Default: 4096 B
