HTML的long属性值

Question

I am wondering why some of the tags attribute values have such a long string of values, such as

<script src="default.aspx?_TSM_HiddenField_=ctl00_sm1_HiddenField&amp;_TSM_CombinedScripts_=%3b%3bAjaxControlToolkit%2c+Version%3d4.1.51116.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d28f01b0e84b6d53e%3aen-US%3afd384f95-1b49-47cf-9b47-2fa2a921a36a%3a475a4ef5%3aeffe2a26%3a7e63a579%3a5546a2b%3ad2e10b12%3a37e2e5c9%3a1d3ed089%3a497ef277%3aa43b07eb%3a751cdd15%3adfad98a5%3a3cf12cf1%3a5a682656%3abfe70f69" type="text/javascript"></script>

or sometimes the id of a tag has a long string of value too.

why is that? is that correct or normal? is that possible to decrease the size of that attribute so that i can somehow lower the load of server when it loads the page?

Answer 1

why is that?

Because a bunch of state data is being passed to the server

is that correct

Yes

or normal?

For ASP.NET it is

is that possible to decrease the size of that attribute so that i can somehow lower the load of server when it loads the page?

Possible? Yes. Easy? Probably not as it looks like it does stuff deep inside ASP.NET.

The effort involved (both in writing the code to do so and running it) won't be worth it. It does not take a great deal of server resource to parse a 400 character query string.

Answer 2

If you mean why does ASP.NET bloat html with long attributes or Ids, that's how web forms works, it's ugly but don't worry about your server load.

You can control the way Ids are assigned to controls by changing the ClientIDMode property.

对于您的问题，我不是100％肯定的，但是不必太担心，因为那部分字符对负载的影响是可以忽略的（除非您在烤面包机上运行网站）。

Answer 4

I believe that this is affecting the script tags exclusively. It seems that you are using Telerik' RadScriptManager's Combining Scripts feature .

If you want to reduce the size of the tags (which is not a real problem), you might disable the feature.
