Hi,
We have a situation where we need to strip a
query string from all URLs except ones
matching a particular pattern. However, when I
try the rules below, it redirects to the
homepage for some reason.
In this example, I'd like to strip off the
query string from all URLs except those
involving /resources/blog:
RewriteCond %{REQUEST_URI} !/resources/blog
RewriteCond %{QUERY_STRING} ^start=
RewriteRule (.*) https://guardiandigital.com$1
[L,QSD]
What am I missing?
Thanks,
Dave
To remove the query string, see the QSD flag,
or append a ? at the end of the target.
That's what I'm doing, I think. What am I missing? It
just redirects to the homepage somehow.
Shouldn't I be able to stack RewriteConds in this way,
followed by a RewriteRule?
I have no idea what could be wrong.
Test with curl, and see if you get redirected after the
fact.
I've enabled trace3 to try and figure this out. But line 8 says
"discarding query string, no parse from substitution" and I don't
know why or what really that means.
