Sorry for my stupid question
I tried to write appmod to handle upload file, When uploaded file size > option max_file_size( about 50MB for exp), in out function, we have to return {ehtml, {p,[], "error message"}}, but the out function is called twice and in browser, i see "Connection Interrupted".
This is my code: out(Arg) -> Options = [{max_file_size, 10000000}], Ret = yaws_multipart:read_multipart_form(Arg, Options), case Ret of {done, UploadParams} -> {ehtml, {p,[], "File upload done"}}; {error, Reason} -> ErrDesc = wf:f("Error '~s'", [Reason]), {ehtml, {p,[], ErrDesc}}; {get_more, Cont, NewState} -> {get_more, Cont, NewState}; Other -> {ehtml, {p,[], "other reason"}} end. [/code]
I use debugger to investigated the Arg variables: with 1 upload request, there are 2 different Arg : < Arg = {arg,#Port<0.14942>, {{10,30,255,12},33023}, {headers,"keep-alive", "text/html,applition.... [/code]
< Arg = {arg,#Port<0.14947>, {{10,30,255,12},33076}, {headers,"keep-alive", "text/html,application [/code]
As you see there are 2 CliSock and 2 different Port number are created with only 1 upload request.
I try with normal get request or upload request with file size < max_file_size there are only 1 CliSock and the Arg is only 1, only 1 Port number.
I also tried return HTTP error code 413, which means "Request Entity too large"
