For file types, why is the maximum URL query length restricted to 2048? how can I increase it?

Hi;

 

For file types, why is the maximum URL query length restricted to 2048? how can I increase it and up to what value? When I increased the value to 4096, that did not kick-in. So when a URL query longer than 4096 was requested, it simply went through unblocked. The 2048 limit works perfectly but not 4096.

 

I have increased the value of the system variable: "ecard_max_http_req_uri_len" to 4096, restarted the asm service. However, this did not make a difference.

 

 

Kindly

Wasfi

ecard_max_http_req_uri_len should be set to a value that is greater than

(URL Length + Query String Length)

from the policy URLs.

 

However, increasing ecard_max_http_req_uri_len may limit the number of concurrent URI request buffers and increase memory pressure within ASM.
