php - Changing Request URL by the Server -


a sample url of question posted on stackoverflow given below.

http://stackoverflow.com/questions/11227809/why-is-processing-a-sorted-array-faster-than-an-unsorted-array

the above url complete url question on stackoverflow, can load same page using url below (note description @ end deleted):

http://stackoverflow.com/questions/11227809

try loading above url , after page loads, @ address bar, url mentioned @ first.

i think happens when requesting 2nd url this:

  1. stackoverflow searches , finds question id 11227809.

  2. then redirects user original url.

are assumptions correct? how can php? (just background of how-to, , know stackoverflow written in asp.net)

you can store slugs contents ids. if @ $_server you'll find requested url. if not contain slug can in db , redirect it.

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!
