You are right this is like a normal link, and yes that is _exactly_ we need, but we also need parameters to be specified for this as this is hostless. The moment I add 'params" core will do different connections which do not work for us. I am okay if you have something else in mind which solves our problem :) Thanks --=20 ~Vinod --3eH4Qcq5fItR5cpy Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBAgAGBQJWcXmmAAoJEHwUBw8lI4NHsaUQAJaeFdhzjImIS87rFjFHF6ZD ZUPWYdfxKQVyD65OV9DoWub1BKQ3M7Uu7qgb19vXNZ4tOO3iE5GV9b8cWPi52cQe NRfLVU6L5HsvvHw/X4TmWHcmAvQuyxJtU5gbwUs4DlX8NE/XmfPh87kOXoGaJNWU P+aYnNk91FvmfA8sqzV183oAe+sWzG72ur51KGdyuQziIbHsKdW/lQ+BfZ69hU87 XeeRbpkia7cdOO7Ypyv88+Zvf02Gmg8WUT3vGdhOFc0xEnIxjDJmYFBCmGCu+OWi Zh+a4V1xOQXXWWK78wM0TzpJdJQcrsggwdkCP5cPRfaYR3INCf1BhY+o/A00+ull 7dAW8f7Zj5hGxgDEu4m6RxFJJpmbjhu1gXMdFaC4x/dNLJqA8RNBGwb7Kb6qOdwI qTlD/81+FNiw5PTwVPkmp7eGHCqhUmhxCTItctvUU0n9TL0fSnIbj/kkOF+mNDa/ jnfsUImOG9Sq1m6KR7RkgzEJ5H+W+dG+jNNSPZgZf+T1Rqq97k7i3Br3rKmZw+cV kW541vwct0mE1UttrThiS3BpLB0YQZanOxQdB90wG2//osVCBqjRIbFEYGjR++tV IcGSiFy8kRAxSFsBDhkoHJGQNWfXEX1YiVz9ldMoKOrgaOpnXNzNUwib4UWDgNu5 FsXfHzUgrqESauh+eUYU =8SBG -----END PGP SIGNATURE----- --3eH4Qcq5fItR5cpy-- --===============2106003215148899025== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline --===============2106003215148899025==--
