safe character to separate multiple urls

Question

I am preparing a special string, in which keys are values are concatenated like below:

username=foo&age=24&[email protected]&homepage=http://foo.com

& is the separator for two key=value pairs
value is url encoded

I have a scenario where there are multiple home pages for a user. I want to specify multiple urls for the homepage key

name=foo&age=24&[email protected]&homepage=url1<some_safe_url_separator_char>url2<some_safe_url_separator_char>url3

We have no control/idea over what url1, url2, .. may contain?

What is a good choice of some_safe_url_separator_char?

In other words I am not looking for a safe character to be used IN a url, but a safe character to be used to SEPARATE two urls in a string

you can use a `JSON` to pass data.instead of making a bulky url — Divya, Nov 03 '14 at 17:05
Could you not pass multiple homepage variables? `name=foo&age=24&[email protected]&homepage=url1&homepage=url2&homepage=url3` [see here](http://stackoverflow.com/questions/1746507/authoritative-position-of-duplicate-http-get-query-keys) — Holloway, Nov 03 '14 at 17:05
@Ashes JSON is not a choice, that I can make. The format is fixed — smc, Nov 03 '14 at 17:08
@Trengot I cannot repeat the same key; the parser is not designed to parse repeated keys — smc, Nov 03 '14 at 17:08

well you can use URL re-writing for this .

It will make a URL that will be safe as it will hide the name of parameters

For refrence you can use URL rewriting

URL rewriting will make a url seprated by '/' and its tough to be decoded by an external person. you can follow links i'm posting
