setting base URL of relative URL starting with slash












0















I am building a reverse proxy with virtual path applications, so that people can visit target site by visiting my site with a top directory indicating which site they are visiting. For example,



https://example-mysite.net/google/


will be redirected to



https://google.net


problem is that in the body of returned html, all links still point to google.net and will not go through my proxy, so I need to rewrite all URLs in body



absolute urls are easy to find using regex, and I found out that I can set the base URL of relative URLs by using the "base" tag, for example, if I write



<base href="https://example-mysite.net/google/">


relative URLs in the body like



<img src="stickman.gif">


will be redirected to https://example-mysite.net/google/stickman.gif, and this will be correctly resolved by my proxy and redirected to https://google.net/stickman.gif



the problem is, relative URLs starting with slash like



<img src="/path/to/root/resource">


will visit https://example-mysite.net/path/to/root/resource, which obviously is not what I want since I have no idea where should I redirect this request.



Is there a way to solve this problem, so that I do not lose the top directory I specified in the base tag?
