Try verification again, and this time send the DELETE HTTP method.

You can simply append to Extra Headers: Access-Control-Allow-Methods GET, POST, OPTIONS, DELETE. What if you want to support OPTIONS and DELETE, as well? For a more conservative and more secure approach, you would allow access only through a particular trusted site.īy default, CORS supports the following methods: PUSH, GET and HEAD. The easiest (and most permissive) value to assign the CORS header is *, which indicates that any site may access your page’s resources. The Access-Control-Allow-Origin header protects from cross-origin resource sharing (CORS) attacks by specifying which websites are allowed to access the resources of your page. You can also use any security header tool, such as Probely’s Security Headers tool to see which headers are detected on your site. Verify the HeadersĬheck the headers for a page on your site, and verify that you see all of the headers you expect. Save the config file, and perform a graceful restart of the web server via systemctl restart lsws.

Look for the context / section and manually add the extra headers within that section. Open the config file of your vhost with the editor of your choice such as Vi or Nano. Other vhosts can be usually found under /usr/local/lsws/conf/vhosts/. You can find the preinstalled example vhost configuration file at /usr/local/lsws/conf/vhosts/Example/nf. Log into your server via ssh and locate your OLS virtual host configuration files.

They are directives that instruct the browser on how to guard against threats, secure connections, control device feature access, and manage information flow between sites.

Security response headers are used on the client and server side.
