Class Web

java.lang.Object

com.codename1.backend.Web

public final class Web
extends Object

Outbound HTTP and HTTPS for server-side binaries. Backed by libcurl, so TLS verification, redirects, chunked decoding and the system certificate store all come from a library that is maintained for the purpose.

Distinct from Http, which is a raw-socket plaintext client for the host runtime's loopback control protocol. Use this one for anything real.

Certificate store. A dynamically linked build finds the system CA bundle. A fully static build has whatever the image provides, which for a scratch container is nothing - and TLS then fails with "unable to get local issuer certificate". Ship a ca-certificates.crt and point curl at it with the CURL_CA_BUNDLE or SSL_CERT_FILE environment variable; both are read by libcurl itself, so no code here has to know about it.
