Support for file://

Hi,

I would be nice if wget would also support file://.

How to debug wget ?

[Jinhui Li]

I am browsing the source code. And want to debug it to figure out how it
works.

So, somebody please tell me how to debug ( with GDB ) or where can I find
information that I need.

Sorry, if i bother you.

Compile Wget with debug informations (-g flag for GCC) and then run wget into
GDB. You can now use and see variables name, structs, function name instead
of unfriendly adresses and raw bytes, ...

I can't show every aspect of GDB. Use your favorite search engine for
more usage info.

BUG : 202329 IF-MODIFIED-SINCE

[vinothkumar raman]

Hi all,

We need to give out the time stamp the local file in the Request
header for that we need to pass on the local file's time stamp from
http_loop() to get_http() . The only way to pass on this without
altering the signature of the function is to add a field to struct url
in url.h

Could we go for it?

Thanks,

Re: [bug #20329] Make HTTP timestamping use If-Modified-Since

[vinothkumar raman]

This mean we should remove the previous HEAD request code and use
If-Modified-Since by default and have it to handle all the request and
store pages if it is not returning a 304 response

Is it so?

 Follow-up Comment #4, bug #20329 (project wget):

 verbatim-mode's not all that readable.

 The gist is, we should go ahead and use If-Modified-Since, perhaps even now
 before there's true HTTP/1.1 support (provided it works in a reasonable
 percentage of cases); and just ensure that any Last-Modified header is sane.
