Are you trying to open/load  div1 from xyz in abc? ( and anchor is in abc rt?)

I dont have answers for your question, but some alternatives may be helpful.

you can try using  directives for the content of div and use logic tag to determine which content you want to include.

Or you can create a template and reload with new contents.

If you use struts, you can use tiles and define that section to be dyanmic .
