Overview of configuration options for the Nette HTTP.
If you are not using the whole framework, but only this library, read how to load the configuration.
http: # headers that are sent with each request headers: X-Powered-By: MyCMS X-Content-Type-Options: nosniff X-XSS-Protection: '1; mode=block' # affects header X-Frame-Options frames: ... # (string|bool) defaults to 'SAMEORIGIN'
For security reasons, the framework sends a header
X-Frame-Options: SAMEORIGIN, which says that a page can be
displayed inside another page (in element
<iframe>) only if it is on the same domain. This can be unwanted in
certain situations (for example, if you are developing a Facebook application), so the behavior can be changed by setting
frames: http://allowed-host.com or
Content Security Policy
Content-Security-Policy (hereinafter referred to as CSP) can be easily assembled, their description can be
found in CSP description. CSP directives (such as
be written either as strings according to specification or as arrays of values for better readability. Then there is no need
to write quotation marks around keywords such as
'self'. Nette will also automatically generate a value of
'nonce-y4PopTLM==' will be send in the header.
http: # Content Security Policy csp: # string according to CSP specification default-src: "'self' https://example.com" # array of values script-src: - nonce - strict-dynamic - self - https://example.com # bool in the case of switches upgrade-insecure-requests: true block-all-mixed-content: false
<script n:nonce>...</script> in the templates and the nonce value will be filled in automatically.
Making secure websites in Nette is really easy.
Content-Security-Policy-Report-Only (which can be used in parallel with CSP) and Feature Policy can be added:
http: # Content Security Policy Report-Only cspReportOnly: default-src: self report-uri: 'https://my-report-uri-endpoint' # Feature Policy featurePolicy: unsized-media: none geolocation: - self - https://example.com
You can change the default values of some parameters of the Nette\Http\Response::setCookie() and session methods.
http: # cookie scope by path cookiePath: ... # (string) defaults to '/' # which hosts are allowed to receive the cookie cookieDomain: 'example.com' # (string|domain) defaults to unset # to send cookies only via HTTPS? cookieSecure: ... # (bool|auto) defaults to auto # disables the sending of the cookie that Nette uses as protection against CSRF disableNetteCookie: ... # (bool) defaults to false
cookieDomain option determines which domains (origins) can accept cookies. If not specified, the cookie is
accepted by the same (sub)domain as is set by it, excluding their subdomains. If
cookieDomain is specified,
then subdomains are also included. Therefore, specifying
cookieDomain is less restrictive than omitting.
For example, if
cookieDomain: nette.org is set, cookie is also available on all subdomains like
doc.nette.org. This can also be achieved with the special value
The default value of
auto which means that if the website is running on HTTPS,
cookies will be sent with the
Secure flag and will therefore only be available via HTTPS.
If the site is running behind an HTTP proxy, enter the IP address of the proxy so that detection of HTTPS connections works
correctly, as well as the client IP address. That is, so that Nette\Http\Request::getRemoteAddress() and isSecured() return the correct values and links are generated with
https: protocol in the templates.
http: # IP address, range (ie. 127.0.0.1/8) or array of these values proxy: 127.0.0.1 # (string|string) defaults to none
Basic sessions settings:
session: # shows session panel in Tracy Bar? debugger: ... # (bool) defaults to false # inactivity time after which the session expires expiration: 14 days # (string) defaults to '3 hours' # when to start the session? autoStart: ... # (smart|always|never) defaults to 'smart' # handler, service that implements the SessionHandlerInterface interface handler: @handlerService
autoStart option controls when to start the session. The value
always means that the session is
always started when the application starts. The
smart value means that the session will be started when the
application starts only if it already exists, or at the moment we want to read from or write to it. Finally, the value
never disables the automatic start of the session.
session: # 'session.name' written as 'name' name: MYID # 'session.save_path' written as 'savePath' savePath: "%tempDir%/sessions"
The session cookie is sent with the same parameters as other cookie, but you can change these for it:
session: # which hosts are allowed to receive the cookie cookieDomain: 'example.com' # (string|domain) # restrictions when accessing cross-origin request cookieSamesite: None # (Strict|Lax|None) defaults to Lax
These services are added to the DI container:
