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.

    Hi Saravana Prakash, 

    Were you able to change the LimitRequestLine  on AEMaaCS, can you please let know if you were able to resolve this and what was the solution for it.

     

    Thank you!

    Yes, we were able to fix this by setting under  

    <VirtualHost *:80> LimitRequestFieldSize 32768 </VirtualHost>

    of our myproject.vhost file. to be safer, duplicated this setting in ALL vhost files having `<VirtualHost *:80>
