Longtable breaks afterpage

Question

My problem is that I want to have a certain footer on the first, or the last, page. The solution I've tried with is by using fancyhdr together with afterpage.

Here is a working example, without longtable, of what I want.

\documentclass[12pt,a4paper]{article}
\usepackage{fancyhdr}
\usepackage{longtable}
\usepackage{afterpage}
\pagestyle{fancy}
\begin{document}
\lfoot{
    Footer page 1
}%end lhead eller lfoot
\afterpage{\clearpage
    \lfoot{
        Footer page 2 and forward
    }%end lfoot
}%end afterpage

Test page 1
\newpage
Test page 2
\newpage
Test page 3
\end{document}

As you can see, the left footer are different on page 1 vs page 2 and 3.

But when I use a longtable which spans over these pages, the afterpage-technique don't work. Unless I force a newpage, which I really don't want to do. As you can see in the following example:

\documentclass[12pt,a4paper]{article}
\usepackage{fancyhdr}
\usepackage{longtable}
\usepackage{afterpage}
\pagestyle{fancy}
\begin{document}
\lfoot{
    Footer page 1
}%end lhead eller lfoot
\afterpage{\clearpage
    \lfoot{
        Footer page 2 and forward
    }%end lfoot
}%end afterpage
\begin{longtable}{|l| l|}
Lots of lines& like this.\\
...
Lots of lines& like this.\\
\end{longtable}
After longtable
\newpage
After newpage
\end{document}

Answer 1

Both \afterpage and longtable act during the phase in which TeX ships out a page, so they are very likely to enter in conflict with each other.

Using \afterpage for the purpose of changing footer after the first page is not recommendable.

\documentclass{article}

\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\fancyfoot[L]{footer for all pages}

\fancypagestyle{firstpage}{%
  \fancyhf{}%
  \fancyfoot[L]{footer for page 1}%
}

\begin{document}
\thispagestyle{firstpage}

<any contents>

\end{document}
