TYPO3 Core

Situation:
Typo3 directory: http://server1/typo3
Another web app: http://server1/webapp

When i insert in the rtehtmlarea a new external link to http://server1/webapp/webapp.php the url will be converted to <LINK webapp/webapp.php> (so it is in the database).

Now when ich click the link it points to http://server1/typo3/webapp/webapp.php, which is wrong.

My PageTSConfig:

RTE {
default {
disableSelectColor = 1
hideButtons = textstylelabel, textstyle, fontstyle, fontsize, lefttoright, righttoleft, user
hidePStyleItems = H4, H5, H6, PRE
proc {
dontHSC_rte = 1
allowTags = table, tbody, tr, th, td, h1, h2, h3, div, p, br, span, ul, ol, li, pre, blockquote, strong, small, em, b, i, u, sub, sup, strike, a, img, nobr, hr, center, font, tt, q, cite, abbr, acronym
denyTags >
exitHTMLparser_rte = 1
exitHTMLparser_rte {
allowTags < RTE.default.proc.allowTags
denyTags < RTE.default.proc.denyTags
}
entryHTMLparser_db = 1
entryHTMLparser_db {
// TAGS ALLOWED
allowTags < RTE.default.allowTags
// XHTML COMPLIANCE
xhtml_cleaning = 1
// AVOID TO HSC TWICE
// htmlSpecialChars = 0
// CLEAN TAGS
noAttrib = b, i, u, strike, sub, sup, strong, em, quote, blockquote, cite, tt, br, center
tags.hr.allowedAttribs = class
// REMAP B AND I TAGS
tags.b.remap = strong
tags.i.remap = em
// REMOVE OPEN OFFICE META TAGS
removeTags = sdfield
// PROTECT CUSTOM TAGS
keepNonMatchedTags = protect
}
}
}
}
