In handler:
ap_internal_redirect(char* uri, request_rec r):
redirect one file to another:
if (strcmp(r->uri,"/path/somefile.html") == 0) {
ap_internal_redirect("/path/newfile.html",r);
return OK;
}else{
return DECLINED;
}
conditional redirect - (test uri to make sure you don't redirect to same file and create loop):
if (some_condition && strcmp(r->uri,"/path/newfile.html") != 0) {
ap_internal_redirect("/path/newfile.html",r);
return OK;
}else{
return DECLINED;
}
uri is path relative to site root.
Note that url in browser location bar will not change, so beware of caching issues.
I also observed that if setting cookies before the redirect, they may not get set when you expect them to.
There is also ap_internal_redirect_handler, but I haven't explored the difference.
