If you need to serve a larger file, consider returning a signed, temporary S3 URL that your user may use to download the file directly from S3. ## [​](#configuring-openssl)Configuring OpenSSL To use certain OpenSSL functions such as [openssl_pkey_new](https://www.php.net/manual/en/function.openssl-pkey-new.php), you must create an `openssl.cnf` configuration file and instruct Vapor to load it via the `OPENSSL_CONF` environment variable. For example, this environment variable will instruct Vapor to load an `openssl.cnf` file from the root of your project: CopyAsk AI``` OPENSSL_CONF="/var/task/openssl.cnf" ``` An example `openssl.cnf` file is available below: CopyAsk AI``` dir = certificates [ ca ] default_ca = CA_default [ CA_default ] serial = $dir/serial database = $dir/index.txt new_certs_dir = $dir/newcerts certificate = $dir/cacert.pem private_key = $dir/private/cakey.pem default_days = 36500 default_md = sha256 preserve = no email_in_dn = no nameopt = default_ca certopt = default_ca policy = policy_match [ policy_match ] commonName = supplied countryName = optional stateOrProvinceName = optional organizationName = optional organizationalUnitName = optional emailAddress = optional [ req ] default_bits = 2048 default_keyfile = priv.pem default_md = sha256 distinguished_name = req_distinguished_name req_extensions = v3_req encyrpt_key = no [ req_distinguished_name ] [ v3_ca ] basicConstraints = CA:TRUE subjectKeyIdentifier = hash authorityKeyIdentifier = keyid:always,issuer:always [ v3_req ] basicConstraints = CA:FALSE subjectKeyIdentifier = hash ``` ## [​](#%E2%80%9Cafter-response%E2%80%9D-jobs)“After Response” Jobs In typical Laravel applications, you may dispatch jobs that will be executed after the HTTP response is sent to the browser: CopyAsk AI``` Route::get('/', function () { dispatch(function () { Mail::to('[[email protected]](/cdn-cgi/l/email-protection)')->send(new WelcomeMessage); })->afterResponse(); return view('home'); }); ``` However, we recommend that you always dispatch jobs to your queue workers when using Vapor. Vapor is not able to execute a job after sending a response to the browser; therefore, attempting to do so will cause your application to appear slower to the end user. ## [​](#inertia-ssr)Inertia SSR Currently, Inertia server-side rendering (SSR) is not available on Vapor environments due to constraints of AWS Lambda. For applications requiring [Inertia with SSR capabilities](https://inertiajs.com/server-side-rendering), we recommend: - **[Laravel Cloud](https://cloud.laravel.com/docs/compute#inertia-ssr)** - Our fully-managed Laravel application platform. - **[Laravel Forge](https://forge.laravel.com/docs/sites/applications#inertia-server-side-rendering)** - Our VPS server management platform.
