I want to create a slave site that will be a replica of the master site except for few menu differences.
So any updates on the master site should be also updated on the slave site automatically.

Iam using Joomla 1.5
Sh404sef
SEF url is switched on in global configuration.
Multi site 1.2.31

When clicking on any article or any link should still stay in the slave site only. MAster site and slave site are distinct sites.

Can any of the multi sites Extension help me in this.

When using the menu sharing will it allow me to continue in the slave site only or does it redirect to master site.

If your question concern the synchronisation of menu between websites, JMS Multisites does not provide that.
What you can do with the "Multisites Menu Item" is to create a bridge between websites.
This does not syncrhonise but compute dynamically the link with current values.

If your question is relative to the update of content then you have to enumerate which content.
The word content is generic.
With JMS Multisites, you can share a limited number of extension and therefore a limited number of content.
See the list of extensions that can be shared.

If you want to share the articles, you have the "Article Sharing for JMS" that allow reading any article coming from any websites defined in JMS Multisites.
