Hi,
I have the following scenario :
- Apache/2.2.19 (Solaris 10 SPARC)
SetInputFilter alterxmlbody (AP_FTYPE_RESOURCE)
SetHandler weblogic-handler
The handler forwards requests to multiple weblogic servers
and the filter itself analyzes and/or changes the POST data
in a way that the length of the incoming request may be changed.
The question is :
What is the proper and legitimate way to deal with this situation?
Should the input filter set the new CL value in "headers_in" before
returning from the callback, or just remove it from the list?
apr_off_t length;
apr_brigade_length (bb,1,&length);
apr_table_setn(f->r->headers_in, "Content-Length", apr_off_t_toa(f->r->pool,
length));
Unfortunately, this approach breaks the pipeline because sometimes
the filter needs to buffer data over more than one call, but I do not
consider this as a problem.
or
apr_table_unset(f->r->headers_in, "Content-Length");
You didn't tell how your handler works (how it forwards the request)
but removing the Content-Length header is probably easiest.
To my knowledge this can be done as follows:
- When "ap_init_filter_func" callback is invoked
(before the handler requests data from the client)
- within "ap_in_filter_func" callback.
I tried but it didn't help, infact it didn't work at all.
Does the
upstream server understand HTTP/1.1 or HTTP/1.0 with a TE header?
Yes, It understands HTTP/1.1.
Do you suggest chunked transfer encoding?
Thanks for the help.
Best regards,
Ivan
