An easy way to increase the number of form input-fields past 10 for a multipart
request
in Tomcat 11.0.8 would be:
/usr/local/tomcat/conf/server.xml
...
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
maxPartCount="100" /> <!— * add here * —>
...
Mark, is there a solution in HttpServlet#doPost, #init(), or @MultipartConfig?
Greetings,
Fabian
