x-dynatrace header max length

Hello. Can anybody tell me - max length of x-dynatrace header. Customer setting up firewall rules, so they need max length all request headers to allow application work, otherwise requests are blocked.

Thanks.

I don't believe there is a size limit from a Dynatrace perspective. Typically, the HTTP header size limit is dependent on the server. (Apache, Nginx, IIS, Tomcat)

I need value from Dynatrace. Expected answer - for example 200 symbols.

Look like this:

FW4;-712055999;35;-1057699572;862004;0;1310537445;1367;c15c;2h01;3hc0f4c90c;4h0d2734;6h6765016c4c42ea4085044906606ef4e6;7hc487f83ef5f244e3

This header added by Dynatrace. Only Dynatrace can know it. The question is not about web server settings.

Thanks,

Alex

Hi,

Unfortunately the header length is not fixed. Depending on the situation encoded binary info will be added to header.
