How to set max-http-header-size in spring boot 2.x application
From Spring boot 2.1, you will now need to use a DataSize
parsable value. e.g.
server.max-http-header-size=40KB
In spring boot 1.3.5.RELEASE what worked for me is setting the following entry in application.properties:
server.tomcat.max-http-header-size=100000
Please try server.max-http-header-size
. I have found it here: Common application properties.
The default value for Tomcat and Jetty is 8KB and for Undertow is 1MB.
You should set on the "application.properties" file:
server.max-http-header-size=48000
48000 is an example of an excessive header, put whatever you want.
