Keeping a website session alive in C# using WebRequest or WebBrowser control? -


i trying keep session alive using either webrequest or webbrowser control. works on websites without problem particular website logging me off after 30 mins.

what ask 1 of website page @ random interval (1-10 mins) using navigateto function in webbrowser control. websites captcha login, first ask user login, cookies , use them webrequest requests , reuse webbrowser control keep alive website (so webbrowser , webrequest clients share same cookies).

i looking ideas, maybe can me out. in advance!

usually, there's nothing can session timeouts, they're both client-side , server-side, or server-side. if you're lucky, though, site in question relies on cookie timeouts, client-side. should case, can play around httpcookie.expires.

this prevent expiring:

httpcookie cookie = ...; cookie.expires = default(datetime);

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
