How to Modify HttpURLConnection Request Size Limits in Tomcat?

Modifying HttpURLConnection Request Size Limits in Tomcat

Sending data over an HttpURLConnection to Tomcat may be subject to size restrictions. Configuring these limits requires modifying two settings within Tomcat's configuration files.

Server Connector Configuration

Within the conf/server.xml file, locate the element that corresponds to the HTTP port you are using. Within this element, modify the maxPostSize attribute:

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

In this example, the maximum request size is set to 65MB.

Manager Web Application Configuration

In the webapps/manager/WEB-INF/web.xml file, locate the element within the element. Update the max-request-size attribute:

<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>

Here, the maximum request size is set to 52MB.

After making these modifications, restart Tomcat to apply the configuration changes and allow for larger HttpURLConnection request sizes.
