Never ever forget the ContentType header when using POST

I have been working on this project that involves sending content from the client to a web server. Actually there are two different projects which were hung up because of one simple ContentType header. Here is the line of code that I was missing out which was causing so much problems for the past few days.
m_WebRequest.ContentType = "application/x-www-form-urlencoded"

I had to document it or else I would forget it as time passes by. This is a VB.net project but the same mistake can cause problems in an AJAX scenario when you are trying to post data. If for some wierd reason you feel that your post data is giving you trouble while it works fine in the web browser set the ContentType header.

This is something I have been thinking for a while so here it goes. This is a list of platforms I know of and my choice of what makes sense for a hobbyist programmer like me. Let me first list down all the possible platforms and then list down the pros and cons that I feel are associated with each platform. Java ME (The platform formally known as J2ME) Windows Mobile Linux Palm Brew Symbian Blackberry iPhone iPhone Let me start with iPhone the darling of the media and blogger's till about a fortnight.

What ever tools the community had built have been rendered useless with the iPhone 1.1.1 software upgrade . The community might be able to hack a version for 1.1.1 but without any support from almighty apple its just a cat and mouse game. With every minor release the applications

Airtel 16Mbps for Impatient Ones

This advert can be the summed as the best in terms of making fun of the impatient ones. The new Airtel broadband is 16 Mbps but with a slight hitch. At Rs. 2999/- with a Data Transfer Limit of just 20 GB. Just listening to a few hours of music videos on Youtube should be enough to exhaust the limit in no time. Thinking of downloading torrents is something one should not even think about. Not sure who Airtel is targeting with this plan. If you bought this plan do leave a comment.
