Default Resume on Upload (FXP)

i upgraded from build 475 (1999) to build 775 & 800 and found out that the upload resume is working icncorrectly now.

It works correctly with G6 FTP Server but somehow it dont work anymore correctly with os/2 ones.

Some Experience i have done shows me , that newer flashfxp builds doesnt send anymore the APPE command to append data to the remote system.

It only sends the REST Command.

As a result of this, the files that will be appended on new Builds (775+800) fails a CRC32 chek

The old build (475) sends the APPE command and all files that was appended have a valid CRC32 checksum.

As i what i said before , it seems some server doesnt need APPE command to be send and work correctly with REST command alone.


This follwing Ã*s a hardcopy of the status log from Flash build 800 :
200 Data port set
STOR dnl-rvw.001
150 OK, opening data connection.
RETR dnl-rvw.001
150 Opening BINARY mode data connection for file dnl-rvw.001 (20000000 bytes).

Transferred: dnl-rvw.001 20.000.000 bytes in 00:05 (3.906,25 KB/sec)

(i use the Break command during upload to create a incomplete file that i resume then)

As this log show,s the "APPE" command wil be send before the "REST" command.

This file will NOT FAIL the CRC32 checksum test.

Looks like some FTP Servers need the APPE command to be send.

Is this a BUG in newer Flash builds ???

Some ftp servers require APPE and others REST/STOR, the majority of the ftp servers we tested supported the later method so we decided to make it the default.

This option can be changed, go into the Site Manager / Options Tab, and check "Use APPE to resume uploads"

The Problem is that in Preferences the option "use APPE to resume upload" is checked.

FlashFxp seems to ignore this setting and does not use APPE to resume uploads.

I even closed and restarted the program, its still the same.

Thing there is a bug in the code since it does not react to this switch.

You're correct the default value is not being set. You can force the site to use APPE by checking the option per site, via the Site Manager / Options Tab. Giving it a solid checkmark.

I will address this in the next public beta release.
