Description
The connection shall be actively closed. Reset the sent- and recv-callbacks.
End of file: either close the connection (Connection: close) or close the file (Connection: keep-alive)
Try to send more data on this pcb.
Get the file struct for a 404 error page. Tries some file names and returns NULL if none found.
Free a struct http_state. Also frees the file data if dynamic.
The connection shall be actively closed (using RST to close from fault states). Reset the sent- and recv-callbacks.
Sub-function of http_send(): end-of-file (or block) is reached, either close the file or read the next block (if supported). @returns: 0 if the file is finished or no data has been read 1 if the file is not finished and data has been read
Try to find the file specified by uri and, if found, initialize hs accordingly.
When data has been received in the correct state, try to parse it as a HTTP request.
Initialize a struct http_state.
Free a struct http_state. Also frees the file data if dynamic.
Sub-function of http_send(): This is the normal send-routine for non-ssi files @returns: - 1: data has been written (so call tcp_ouput) - 0: no data has been written (no need to call tcp_output)
Sub-function of http_send(): This is the send-routine for ssi files @returns: - 1: data has been written (so call tcp_ouput) - 0: no data has been written (no need to call tcp_output)
Extract URI parameters from the parameter-part of an URI in the form "test.cgi?x=y" @todo: better explanation! Pointers to the parameters are stored in hs->param_vals.
Insert a tag (found in an shtml in the form of "" into the file. The tag's name is stored in ssi->tag_name (NULL-terminated), the replacement should be written to hs->tag_insert (up to a length of LWIP_HTTPD_MAX_TAG_INSERT_LEN). The amount of data written is stored to ssi->tag_insert_len. @todo: return tag_insert_len - maybe it can be removed from struct http_state?
