The plus sign is what spaces get encoded to when a string such as a file name gets url encoded.

My guess is this legacy app actually had spaces in the file names, which most experienced web developers would not do. In fact we strip out spaces in urls entered by users in mojoportal (at least in url manager, not sure about 301 redirect manager).

I guess you might try going directly into the the database if the ui doesn't let you try using spaces instead of plus signs. I'm not sure that will solve it but it might.

Hope that helps,

If you have control of the machine and it uses IIS 7.x then you might take a look at the IIS Url Rewriter module. You "may" be able to configure it to do the 301 redirects based on a pattern. This url rewriting happens before the request would even get to mojoPortal. Be careful though as a mistake in the redirect pattern can cause unexpected results with other urls.

Best,

Joe
