Put `http.request.method == &quot;POST&quot;` in the display filter of wireshark to only show POST requests.  Click on the packet, then expand the Hypertext Transfer Protocol field.  The POST data will be right there on top.

You will have to use some sort of network sniffer if you want to get at this sort of data and you&#39;re likely to run into the same problem (pulling out the relevant data from the overall network traffic) with those that you do now with Wireshark.

I have a DataTable that returns

    IDs
    ,1
    ,2
    ,3
    ,4
    ,5
    ,100
    ,101

I want to convert this to single string value, i.e:

    ,1,2,3,4,5,100,101

How can i rewrite the following to get a single string

    var _values = _tbl.AsEnumerable().Select(x =&gt; x);

IEnumerable to string delimited with commas?

I have a table in MySQL that have a few columns that have default values specified, but when I try to insert a row, (not specifying values for those default columns), it throws an error saying I cannot insert NULL values.

Here is the table example;

    CREATE TABLE `users` (
      `Id` int(10) unsigned NOT NULL AUTO_INCREMENT,
      `UniqueName` varchar(120) NOT NULL,
      `Password` varchar(1000) NOT NULL,
      `PublicFlag` tinyint(1) NOT NULL,
      `NoTimesLoggedIn` int(10) unsigned NOT NULL DEFAULT &#39;0&#39;,
      `DateTimeLastLogin` timestamp NOT NULL DEFAULT &#39;1971-01-01 00:00:00&#39;,
      `UserStatusTypeId` int(10) unsigned NOT NULL,
      `Private` tinyint(1) NOT NULL DEFAULT &#39;0&#39;,
      `SiteName` varchar(255) NOT NULL,
      `CountryId` int(10) NOT NULL DEFAULT &#39;0&#39;,
      `TimeZoneId` varchar(255) NOT NULL DEFAULT &#39;UTC&#39;,
      `CultureInfoId` int(10) unsigned NOT NULL DEFAULT &#39;0&#39;,
      `DateCreated` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
      `UserCreated` int(10) unsigned NOT NULL,
      `LastUpdatedBy` int(10) unsigned NOT NULL,
      `DateLastUpdated` datetime DEFAULT NULL,
      PRIMARY KEY (`Id`),
      UNIQUE KEY `UniqueName_UNIQUE` (`UniqueName`),
      KEY `Index 3` (`SiteName`)
    )

It complains about TimeZoneId, and when I populate TimeZoneId, it complains about CultureInforId.

I am using MySQL Version: 5.1.43-community

Here is the insert query I am trying to insert, grabbed from NHibernate Profiler:

    INSERT INTO Users
               (UniqueName,
                Password,
                PublicFlag,
                NoTimesLoggedIn,
                DateTimeLastLogin,
                SiteName,
                TimeZoneId,
                DateCreated,
                DateLastUpdated,
                Private,
                CountryId,
                CultureInfoId,
                UserCreated,
                LastUpdatedBy,
                UserStatusTypeId)
    VALUES     (&#39;zma@zm.com&#39;,&#39;u1uhbQviLp89P9b3EnuN/Prvo3A4KVSiUa0=&#39;,1,
    0,&#39;1/01/1971 12:00:00 AM&#39;,&#39;V9O1T80Q6D&#39;,NULL,&#39;2/08/2010 2:13:44 AM&#39;,
    &#39;2/08/2010 2:13:44 AM&#39;,0, NULL, NULL, 4, 4,31)


MySQL - Cannot insert NULL value in column, but I have a default value specified?

I am coding an SEO tool in C# for doing keyword research. I need to make calls to Google Adword keyword tool. Now I know some tools which are doing the same already.

I just need to decipher what they are doing. I tried using Wireshark but it&#39;s very complex to get the actual POST data using Wireshark.

I tried using fiddler on IE but seems like too many Javascript requests are made which confuses fiddler a lot.

If I can just find out the exact requests the other tool is making I think my job is done. How can I do this?

How are cookies passed in the HTTP protocol?

I&#39;ve only recently been getting involved with PHP/AJAX/jQuery and it seems to me that an important part of these technologies is that of `POST` and `GET`.

First, what is the difference between `POST` and `GET`? Through experimenting, I know that `GET` appends the returning variables and their values to the URL string

    website.com/directory/index.php?name=YourName&amp;bday=YourBday

but `POST` doesn&#39;t.

So, is this the only difference or are there specific rules or conventions for using one or the other?

Second, I&#39;ve also seen `POST` and `GET` outside of PHP: also in AJAX and jQuery. How do `POST` and `GET` differ between these 3? Are they the same idea, same functionality, just utilized differently?

Although it is strongly recommended ([W3C source][2], via [Wikipedia][3]) for web servers to support semicolon as a separator of URL query items (in addition to ampersand), it does not seem to be generally followed.

For example, compare

&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;[http://www.google.com/search?q=nemo&lt;b&gt;&amp;&lt;/b&gt;oe=utf-8][4]

&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;[http://www.google.com/search?q=nemo&lt;b&gt;;&lt;/b&gt;oe=utf-8][5]

results. (In the latter case, semicolon is, *or was at the time of writing this text*, treated as ordinary string character, as if the url was: [http://www.google.com/search?q=nemo&lt;b&gt;%3B&lt;/b&gt;oe=utf-8][6])


Although the first URL parsing library i tried, behaves well:

    &gt;&gt;&gt; from urlparse import urlparse, query_qs
    &gt;&gt;&gt; url = &#39;http://www.google.com/search?q=nemo;oe=utf-8&#39;
    &gt;&gt;&gt; parse_qs(urlparse(url).query)
    {&#39;q&#39;: [&#39;nemo&#39;], &#39;oe&#39;: [&#39;utf-8&#39;]}

What is the current status of accepting semicolon as a separator, and what are potential issues or some interesting notes? (from both server and client point of view)

Semicolon as URL query separator

Can you please describe an example indicating difference between Public and Private Cache-Control in asp.net applications hosted in IIS.

I read in [MSDN][1] that the difference is the following:

**Public:** 
Sets Cache-Control: public to specify that the response is cacheable by clients and shared (proxy) caches.

**Private:** Default value. Sets Cache-Control: private to specify that the response is cacheable only on the client and not by shared (proxy server) caches.

I am not sure I have completely understood the pros and cons from each choice. An example for when to or not to use it would be great. 

For example what should I do if i have two web servers hosting the same application? Is there anything to watch out if I choose Private or Public?

I want to ask a question about the `multipart/form-data`. In the HTTP header, I find that the `Content-Type: multipart/form-data; boundary=???`. 

Is the `???` free to be defined by the user? Or is it generated from the HTML? Is it possible for me to define the `??? = abcdefg`?

I tried `dst==192.168.1.101` but only get :

    Neither &quot;dst&quot; nor &quot;192.168.1.101&quot; are field or protocol names.
    
    The following display filter isn&#39;t a valid display filter:
    dst==192.168.1.101

How to filter by IP address in Wireshark?

Recently, I came across an issue where a CGI application is not responding. Symptom is Firefox displaying:

&gt; Transferring data from localhost...

But the thing is I cannot see any traffic from Firebug&#39;s Net panel, and the browser just stays on the same stage forever.

I am thinking about the ways to debug this application but I cannot see the source code or any of its compiled Java/C++ components, therefore I reckon a HTTP network level of diagnostics is a good start.

I have little experience in Fiddler and Wireshark, just wondering will they get better feedback/statistics in the HTTP network level? I&#39;ve heard Wireshark is advanced but could possibly introduce a large volume of traffic so system admins don&#39;t like it very much. At this time I think Firebug doesn&#39;t really show me enough information.

I need to collect information so that I can then forward to client as proof.

I would like to monitor network traffic of my Android Phone. I was thinking using tcpdump for Android, but I&#39;m not sure if I have to cross-compile for the phone.

Another question is the following, If I want to monitor the trafic data for a certain application, there&#39;s any command for doing that?

I applied a filter in wireshark to display only the incoming packets to my PC. When I save the filtered/displayed packets to a .csv file, I actually saves all the packets (un-filtered). How can I save only the displayed/filtered packets?
