Standard method for HTTP partial upload, resume upload -

-

i'm developing http client/server framework, , looking correct way handle partial uploads (the same downloads using method range header).

but, http put not intended resumed. , patch method, know, doesn't accept range header.

is there way handle in http standard (not using extension headers or etc)?

thanks in advance.

i think there no standard partial uploads:

  • content-range inside requests not explicitly forbidden in rfc2616 (http), wording refers response header gets used in response of range-request
  • while use patch method update existing resource (e.g. add more bytes) not same partial upload, because time incomplete resource available

if @ protocols of dropbox, google drive etc roll own protocol transfer single files in multiple chunks. need resumeable uploads

  • a way address incomplete upload. normal urls address complete, not partial resource , know of no standard partial resources.
  • a way find out current state of upload, maybe checksums of part sure, local file did not change. provided webdav propfind method (once able address incomplete resource :)
  • a way upload chunk. here 1 maybe use patch content-range header. mod_dav seems allow put content-range header (see http://www.gossamer-threads.com/lists/apache/users/432346)
  • a way publish resource once complete, or way define upfront complete means (e.g size of resource, checksum...)

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
