newbie: HTTP and URIs

[Guest]

Hi,

I'm quite new to this, so please excuse trivial questions:

- Is there any function (int the .net framework) that gives me an
enumeration of all URIs in a http stream (passed as e.g. a string)? If not,
how could I achieve such a thing?

- Really trivial, but to make sure: What does the string "/..../" in an URL
mean? I'd suspect some directory operation, but I dunno exactly...

- I'm currently using the HttpUtility.UrlDecode() function to decode some
http URIs and one thing stroke me in particular: The string
[...]"test.exe?/c+xtsr" is decoded to "test.exe?/c xtsr", missing the "+".
When I use the System.Uri class for the decoding the "+" remains....Does
anyone know why?

Thanks for reading till end and thanks in advance

Hi Peter,

No question is trivial if you don't know the answer to it!

- Is there any function (int the .net framework) that gives me an
enumeration of all URIs in a http stream (passed as e.g. a string)? If
not,
how could I achieve such a thing?

Not sure what you mean by this. You can find URLs in an HTML document by
using Regular Expressions. The HTML document is a string.

- Really trivial, but to make sure: What does the string "/..../" in an
URL
mean? I'd suspect some directory operation, but I dunno exactly...

Is that the exact string you saw in a URL? I've never seen it before.

The following link to the W3C should help":

- I'm currently using the HttpUtility.UrlDecode() function to decode some
http URIs and one thing stroke me in particular: The string
[...]"test.exe?/c+xtsr" is decoded to "test.exe?/c xtsr", missing the "+".

The "+" character is a URL-Encoding for a space (which is an illegal URL
character).
