How to increase the size of HTTP Post Request in Websphere

  • 772

The HTTP specification doesn't impose a specific size limit for posts. They will usually be limited by either the web server or the programming technology used to process the form submission.

How i can increase this size for websphere?

  1. To change the size of post request you have to follow these steps :

    1. Open the WebSphere plug-in configuration file (plugin-cfg.xml) in the WAS_HOME/config/cells directory with a text editor.
    2. Locate the ServerCluster stanza with the following name: WebSphere_Portal__Cluster
    3. Associated with this entry, find the parameter PostSizeLimit.
    4. Change to a value in bytes (changing into a value to set a new limit or changing into "-1" to disables limit).
    5. Save the changes and close the file.
    6. Restart the application and portal servers.

    I would recommend to rather change this via the Administrative Console.

    In V7 navigate to Servers -> Server Types -> Web servers -> <servername> -> Plug-in properties -> Request routing.

    In V6 you find this at Servers -> Web Servers -> <servername> -> Plug-in properties -> Plug-in <serverclustername> Properties.

    There, change the Maximum size of request content parameter to No Limit. This sets the PostSizeLimit parameter.

    The advantage is that this should also persist across a new plug-in generation, and is less error-prone.
