Previous mod_proxy release doesn't carry all headers_out across redirect;
I have patched proxy_http.c in apache 1.3.23
In proxy_http.c u find:
/* handle the ProxyPassReverse mappings */
if ((urlstr = ap_table_get(resp_hdrs, "Location")) != NULL)
ap_table_set(resp_hdrs, "Location", proxy_location_reverse_map(r,
urlstr));
if ((urlstr = ap_table_get(resp_hdrs, "URI")) != NULL)
ap_table_set(resp_hdrs, "URI", proxy_location_reverse_map(r, urlstr));
if ((urlstr = ap_table_get(resp_hdrs, "Content-Location")) != NULL)
ap_table_set(resp_hdrs, "Content-Location", proxy_location_reverse_map(r
, urlstr));
resp_hdrs doesn't containd Set-Cookie :(
They have Location, URI & Content-Location
then resp_hdrs is copied onto r->headers_out:
proxy_http.c apache 1.3.23:
/* Setup the headers for our client from upstreams response-headers */
ap_overlap_tables(r->headers_out, resp_hdrs, AP_OVERLAP_TABLES_SET);
After this, cookies are missed.
My patch save cookie before ap_overlap_tables, and then add them to
r->headers_out
in proxy_http.c apache 1.3.26 u find:
/* Setup the headers for our client from upstreams response-headers */
ap_proxy_table_replace(r->headers_out, resp_hdrs);
If Graham is right (as I hope) using ap_proxy_table_replace instead of
ap_overlap_tables
does fix the cookies problem (is it a bug? i dunno..)
I'm missing something?
