Size of a request header field exceeds server limit.

[AEMnewbie]

Where can we find the configuration to update the request header size in AEM dispatcher?

Hi @AEMnewbie ,

You can define the header limit in Apache config file - httpd.conf

LimitRequestLine 16384

This will increase the size to 16KB

Default value is 8KB

Please refer to below documentation

https://httpd.apache.org/docs/2.4/en/mod/core.html#limitrequestline

There are other settings available too, like LimitRequestFields, LimitRequestFieldSize. Please use them as per your requirement.

Thanks,

Chitra

Hi Chitra,

I couldn't find the LimitRequestLine in the httpd.conf file under etc/httpd/conf?

Please let me know where can I find the header size?

Thanks,

VJ

Has anyone faced same issue from AEMCaaS ? So, at cloud manager, we dont have httpd.conf file. I am facing same issue, but unable to resolve. I tried adding LimitRequestFieldSize 16384 to vhost, no effect. Randomly tried at many files, somehow dispatcher is not picking this config.
