[users@httpd] Mod_rewrite removing white spaces from outside url.
Hello, I have an issue where we have Apache 2.4.4.X using
mod_proxy_balancer pointing at Apache Tomcat 8. Our applications returning
an outside url that has space in the url i.e. (www.example.com/myapp/
structs/ somedata/ We want to return this url without spaces because it
fails. I have tried Apache mod_rewrite and the regex below within my
vhost.conf file as well as using it with the Apache tomcat rewrite module
inside of a rewrite.conf file with no success.
I confirmed it was working atleast running by using the trace8 on my
mod_rewrite loglevel. But, what it doesnt do is clean up the spaces in
question.
# remove spaces from start or after /
RewriteRule ^(.*/|)[\s%20]+(.+)$ $1$2 [L]
# remove spaces from end or before /
RewriteRule ^(.+?)[\s%20]+(/.*|)$ $1$2 [L]
# replace spaces by - in between
RewriteRule ^([^\s%20]*)(?:\s|%20)+(.*)$ $1-$2 [L,R]

You are correct the inbound doesn’t have spaces and the redirect returning does so there isn’t anything to rewrite on. Let me work with the development team on the returned values.
I appreciate the help and confirmation as well.

Why guess?

There's no spaces in the URL being requested. What could you rewrite?

Thankyou Eric! :)
Eric, before running I want to confirm that this will work below?
<VirtualHost *:80>
ProxyPreserveHost On
ProxyPass / http://X.X.X.X:8080/login
RewriteEngine On
RewriteRule ^(.*/|)+(%20)+(.+)$ $1$2 [L]
# remove spaces from end or before /
RewriteRule ^(.+?)+(%20)+(/.*|)$ $1$2 [L]
# replace spaces by - in between
RewriteRule ^(^%20*)+(?:%20)+(.*)$ $1-$2 [L,R]
ProxyPassReverse / http://X.X.X.X:8080/login
</VirtualHost>

If there is a literal %20 I don't think this should be in square
brackets. I don't think the \s will ever match so I would drop it at
the same time.

The rewrite rules don't change what's "returned" they modify the URL
requested on the server. Can you attach your rewrite:trace8 output
that fails to modify the URL w/ the improvements above?
