What is the maximum size of HTTP header values?

Web Services server HTTP

Most web servers have their own set of size limits on HTTP request headers. The HTTP Header values are restricted by server implementations. The following are the limits of some of the most popular web servers −

Web Server	Size Limit
Apache	8K
Nginx	4K-8K
IIS	8K-16K
Tomcat	8K – 48K

If the header size exceeds the above limit, the server returns 413 Entity Too Large error.
