I have this class to connect php server

import java.net.HttpURLConnection
import java.net.URL
import java.util.regex.Pattern

class jHttpConnect03(
private val destinationUrl: String
) {

private var urlConnectionTls: HttpURLConnection? = null

private fun chekregexp(url: String, regexp: String): Boolean {
val mPattern = Pattern.compile(regexp)
return mPattern.matcher(url).find()
}

fun checkTlsAndConnect(): HttpURLConnection? {
if ( !chekregexp(destinationUrl, "^(http://)") ) {
return null
}

try {
// Tell the URLConnection
val url = URL(destinationUrl)

urlConnectionTls = url.openConnection() as HttpURLConnection
/*
urlConnectionTls!!.setRequestProperty("Cache-Control",
"no-cache")
urlConnectionTls!!.setDefaultUseCaches(false)
urlConnectionTls!!.setUseCaches(false)

*/
/*
// set none cache
con.setRequestProperty("Cache-Control", "no-cache");

con.setDefaultUseCaches(false);
con.setUseCaches(false);
*/
//urlConnectionTls!!.sslSocketFactory = context.socketFactory
} catch ( _ : Exception ) {
return null
}

return if ( urlConnectionTls != null ) {
urlConnectionTls
} else {
null
}
}

}


I want real disabled cache for HttpConnect but this don't work

urlConnectionTls!!.setRequestProperty("Cache-Control", "no-cache")
urlConnectionTls!!.setDefaultUseCaches(false)
urlConnectionTls!!.setUseCaches(false)


How to fix this?
