[SOLVED] Apache2: 429, Too Many Requests response

Apache2: 429, Too Many Requests response

My Apache returns a 429 error code when I start using my API intensively. De API calls are generated by SAP BusinessObject and send to my 'Reverse Proxy' to convert HTTP to HTTPS. The Reverse Proxy forwards the HTTP request to the webserver over HTTPS.

After 15 requests, the Reverse Proxey returns a 429 error in the Apaches error.log. These 15 requests are made within 9 minutes.

How can I configure Apache so it will handle this kind of load/traffic? Becase I've another 300 requests after the first 15...

Reverse Proxy config:

NameVirtualHost *:80
ProxyRequests Off

<VirtualHost *:80>
        ServerName domain.com
        ServerAlias domain.com

        SSLProxyEngine On
        SSLProxyVerify none
        SSLProxyProtocol SSLv3
        ProxyPass / https://domain.com/
        ProxyPassReverse / https://domain.com/

        <Directory proxy:*>
                Order Deny,Allow
                Allow from all
        </Directory>
</VirtualHost>

Solution

An update in de webserver was the problem. The vendor replaced their webserver and put a limit of 5 requests per minute in the software...

This was not mentioned in the release notes.

Thank you for he time and sorry to bother you.
