How to Configure the Maximum HttpRequest Size in Tomcat?

Configuring Maximum HttpRequest Size in Tomcat

Question:

What is the maximum data size that can be sent in a single HttpRequest to Tomcat? Does it have any limitations?

Answer:

Tomcat has configurable limits for HttpRequest size, which are typically modified in two places:

In conf/server.xml:

<code class="xml"><Connector port="80" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443"
            maxPostSize="67589953" /></code>

The maxPostSize attribute specifies the maximum size for POST requests. By default, this is set to 2MB.

In webapps/manager/WEB-INF/web.xml:

<code class="xml"><multipart-config>
  <!-- 52MB max -->
  <max-file-size>52428800</max-file-size>
  <max-request-size>52428800</max-request-size>
  <file-size-threshold>0</file-size-threshold>
</multipart-config></code>

The max-request-size attribute sets the maximum size for a multipart request. The max-file-size attribute sets the maximum size for individual files in a multipart request. By default, these values are set to 2MB.

To accommodate larger requests, these limits can be increased by modifying the corresponding attributes in the configuration files.
