annotate src/http/ngx_http_variables.c @ 4641:045bb3ef3ffc
Fixed core variables dynamic access after reconfiguration.
If variable was indexed in previous configuration but not in current
one, the NGX_HTTP_VAR_INDEXED flag was left set and confused
ngx_http_get_variable().
Patch by Yichun Zhang (agentzh), slightly modified.
