如何在Android上创建压缩的SSL / TLS连接

Question

i want to have an https connection to the server, but in order to conserve bandwidth i want it to be compressed. I heard that some SSL implementations support compression (i dont mean the zlib encoding of the HTTP payload itself), can it be activated in android? i couldnt find any reference to it neither in javax.net.ssl.HttpsURLConnection nor in javax.net.ssl.SSLServerSocketFactory

Answer 1

SSL and TLS were defined so as to include a compression feature, but it isn't supported in Java JSSE, ie javax.net.ssl.* , at least in Oracle's implementation. Use zip-encoding. The zip-encoding happens to the plaintext content, then SSL is applied over that.

EDIT Not supported by default in anything else except OpenSSL either as of date. ' conservative implementations do not enable compression at the TLS level'
